Publication number: 20230204856Abstract: A semiconductor photonic package can include a laser module and a photonic integrated circuit (PIC), each having a different operating temperature. The two modules are placed on a common substrate allowing accurate optical alignment. In addition, a thermal barrier is integrated into the substrate between the laser module and the PIC to provide thermal stability, especially to the laser module. The substrate can include a housing with good electrical conductivity or an optical substrate and housing. The thermal barrier is integrated into the optical substrate, the housing, or both. The thermal barrier in the optical substrate can be a cutout that does not divide the optical substrate into two separate pieces.Type: ApplicationFiled: December 23, 2021Publication date: June 29, 2023Inventors: Eredzhep MENUMEROV, LU CHENG, Boping XIE

Publication number: 20230204877Abstract: Technologies for beam expansion and collimation for photonic integrated circuits (PICs) are disclosed. In one embodiment, an ancillary die is bonded to a PIC die. Vertical couplers in the PIC die direct light from waveguides to flat mirrors on a top side of the ancillary die. The flat mirrors reflect the light towards curved mirrors defined in the bottom surface of the ancillary die. The curved mirrors collimate the light from the waveguides. In another embodiment, a cavity is formed in a PIC die, and curved mirrors are formed in the cavity. Light beams from waveguides in the PIC die are directed to the curved mirrors, which collimate the light beams.Type: ApplicationFiled: December 23, 2021Publication date: June 29, 2023Applicant: Intel CorporationInventors: John M. Heck, Haisheng Rong, Harel Frish, Ankur Agrawal, Boping Xie, Randal S. Appleton, Hari Mahalingam, Alexander Krichevsky, Pooya Tadayon, Ling Liao, Eric J. M. Moret

Publication number: 20230204876Abstract: Technologies for coupling to and from a photonic integrated circuit (PIC) with an optical isolator are disclosed. In one embodiment, light beams from waveguides on a PIC die are reflected towards flat mirrors on the bottom surface of the PIC die. The flat mirrors reflect the light towards curved mirrors defined in a top surface of the PIC die, which collimate the beam and direct the collimated beams out the bottom surface of the PIC die. An optical isolator below the PIC die can allow the beams to pass while blocking beams in the opposite direction.Type: ApplicationFiled: December 23, 2021Publication date: June 29, 2023Applicant: Intel CorporationInventors: Alexander Krichevsky, Boping Xie

Patent number: 11251228Abstract: Optical receiver packages and device assemblies that include photodetector (PD) chips having focus lenses monolithically integrated on PD die backsides are disclosed. An example receiver package includes a support structure, a PD die, and an optical input device. The PD die includes a PD, integrated proximate to a first face of the PD die, and further includes a lens, integrated on, or proximate to, an opposite second face. The first face of the PD die faces the support structure, while the second face (“backside”) faces the optical input device. The optical receiver architectures described herein may provide an improvement for the optical alignment tolerance issues, especially for high-speed operation in which the active aperture of the PD may have to be very small. Furthermore, architectures described herein advantageously enable integrating a focus lens in a PD die that may be coupled to the support structure in a flip-chip arrangement.Type: GrantFiled: December 19, 2018Date of Patent: February 15, 2022Assignee: Intel CorporationInventors: Boping Xie, Ansheng Liu, Olufemi Isiade Dosunmu, Alexander Krichevsky, Kelly Christopher Magruder, Harel Frish

Patent number: 10838042Abstract: An apparatus comprises a horizontal array of emitter/detector pairs; an array of lens pairs mounted above and aligned with emitter/detector pairs; and a first curved reflective surface positioned such that for each emitter/detector pair and corresponding lens pair, light from the emitter that passes through a lens of the lens pair is redirected into the far field, and light arriving from the far field is redirected through the other lens of the lens pair onto the detector. Light from each emitter is emitted upwards along a vertical axis, and light received by each detector is incident on the detector downwards along a vertical axis. If light emitted from the first array and reflected by the first surface into the far field reflects off an object in the far field and returns to the apparatus, the returning light is reflected off the first surface and detected by the first array.Type: GrantFiled: November 20, 2017Date of Patent: November 17, 2020Inventors: Vipul Dutt Badoni, Michael Patrick Lenihan, Michael John Henderson, Boping Xie, Michael V Morelli, Randy Goettsch

Patent number: 10598875Abstract: Disclosed herein are photonic package assemblies, packages, and devices that include photonic dies and optical coupling structures aligned with photonic dies to enable exchange of electromagnetic signals. In one aspect, a photonic package assembly includes a photonic integrated circuit (PIC) die having one or more PICs, and an optical coupling structure (OCS) positioned adjacent to the PIC die such that electromagnetic signals may be exchanged between at least one of the one or more PICs and the OCS. The assembly further includes a structure that forms a bridge, and, thereby, provides mechanical coupling, between the OCS and the PIC die. Providing a bridge structure that directly attaches an OCS to a PIC die may improve achieving and maintaining the desired alignment between the OCS and the PIC die, which may lead to an improved coupling performance over the lifetime of products.Type: GrantFiled: December 14, 2018Date of Patent: March 24, 2020Assignee: Intel CorporationInventor: Boping Xie

Patent number: 9405082Abstract: Direct pin attachment is the most compact method to connect the OSA and the PCBA, due to better performance in general and allows maximum PCBA space for more functionality. However, direct pin attachment can result in concentrated stress in the OSA-PCBA joint area, which can affect the reliability and yield of the module. To overcome the problem, an integrated transceiver cage and housing is provided including a direct pin attachment with reinforcing tabs, which are fixed to the PCBA prior to the pins to transfer any stress between the OSA and PCBA, thereby reducing the amount of stress applied to the pins.Type: GrantFiled: September 26, 2013Date of Patent: August 2, 2016Assignee: Lumentum Operations LLCInventors: Rui Zhou, Boping Xie
