Patent number: 11699677Abstract: Described herein is a die-to-wafer bonding process that utilizes micro-transfer printing to transfer die from a source wafer onto an intermediate handle wafer. The resulting intermediate handle wafer structure can then be bonded die-down onto the target wafer, followed by removal of only the intermediate handle wafer, leaving the die in place bonded to the target wafer.Type: GrantFiled: June 30, 2020Date of Patent: July 11, 2023Assignee: OpenLight Photonics, Inc.Inventors: Roberto Marcoccia, Benjamin M.

Patent number: 11693195Abstract: An optical pick and place machine that includes a self-calibrating optical controller for error feedback based optical placement of optical components using active alignment is described. The optical controller can include a loopback mode to generate a baseline value of light generated by a light source and measured by a photodetector within the optical controller. The optical controller can further include an active alignment mode in which the light is coupled from the pick and place machine to the optical device on which the component is placed. The optical coupling of the placed component can be evaluated against the baseline value to ensure that the optical coupling is within specification (e.g., within a prespecified range).Type: GrantFiled: July 15, 2022Date of Patent: July 4, 2023Assignee: OpenLight Photonics, Inc.Inventors: Steven William Keck, Roberto Marcoccia, Steve McGowan

Patent number: 11546055Abstract: An optical transceiver can be calibrated using an internal receiver side eye scan generator, and calibration values (e.g., modulator values) can be stored in memory for recalibration of the optical transceiver. The eye scan generator can receive data from the transmitter portion via an integrated and reconfigurable loopback path. At a later time, different calibration values can be accessed in memory and used to recalibrate the optical transceiver or update the calibrated values using the receive-side eye scan generator operating in loopback mode.Type: GrantFiled: June 15, 2021Date of Patent: January 3, 2023Assignee: OpenLight Photonics, Inc.Inventors: Robert S.

Patent number: 10958343Abstract: In some embodiments, an apparatus includes an optical transmitter module that can be electrically coupled to an electrical serializer/deserializer and a controller. The optical transmitter module can include an electrical detector that can receive an in-band signal. The electrical detector can send to the controller a first power error signal and a second power error signal based on the in-band signal. The controller can send a correction control signal to the electrical serializer/deserializer based on the first power error signal and the second power error signal such that the electrical serializer/deserializer sends a pre-emphasized signal to the optical transmitter module based on the correction control signal. In such embodiments, the first power error signal, the second power signal and the correction control signal are out-of-band signals.Type: GrantFiled: June 28, 2019Date of Patent: March 23, 2021Assignee: Juniper Networks, Inc.Inventors: Theodore J.

Patent number: 10700806Abstract: An article may include an optical transceiver package, which may include a photonics component mounted in the optical transceiver package. The photonics component may generate heat in an operational state. The optical transceiver package may include a sealed thermal chamber that maintains the photonics component between a lower predetermined working temperature and a higher predetermined working temperature. The sealed thermal chamber may include a material that exhibits a first thermal conductivity below a lower predetermined threshold temperature and a second thermal conductivity higher than the first thermal conductivity above an upper predetermined threshold temperature. A method may include retaining the generated heat to raise the photonics component above a lower predetermined working temperature, and conducting the generated heat away from the optical transceiver package to lower the photonics component below an upper predetermined working temperature.Type: GrantFiled: April 4, 2019Date of Patent: June 30, 2020Assignee: Juniper Networks, Inc.Inventors: Theodore John Schmidt, Roberto Marcoccia
