Patent number: 8781283Abstract: Embodiments of the invention relate to an electro-optic device comprising a first region of silicon semiconductor material and a second region of III-V semiconductor material. A waveguide of the optical device is formed in part by a ridge in the second region. An optical mode of the waveguide is laterally confined by the ridge of the second region and vertically confined by a vertical boundary included in the first region. The ridge structure further serves as a current confinement structure over the active region of the electro-optic device, eliminating the need for implantation or other structures that are known to present reliability problems during manufacturing. The lack of “voids” and implants in electro-optic devices according to embodiments of the invention leads to better device reliability, process repeatability and improved mechanical strength.Type: GrantFiled: January 18, 2013Date of Patent: July 15, 2014Assignee: Aurrion, Inc.Inventors: Alexander W.

Patent number: 7643532Abstract: The present invention relates to the tailoring the reflectivity spectrum of a sampled-grating distributed Bragg reflector (SGDBR) by applying digital sampling theory to choose the way each reflector is sampled. The resulting mirror covers a larger wavelength span and has peaks with a larger, more uniform, coupling constant (?) than the mirrors produced using conventional approaches. The improved mirror also retains the benefits of the sample grating approach. Additionally, most of the embodiments are relatively simple to manufacture.Type: GrantFiled: July 13, 2005Date of Patent: January 5, 2010Assignee: JDS Uniphase CorporationInventors: Gregory A.

Patent number: 7633988Abstract: A monolithically-integrated semiconductor optical transmitter that can index tune to any transmission wavelength in a given range, wherein the range is larger than that achievable by the maximum refractive index tuning allowed by the semiconductor material itself (i.e. ??/?>?n/n). In practice, this tuning range is >15 nm. The transmitter includes a Mach-Zehnder (MZ) modulator monolithically integrated with a widely tunable laser and a semiconductor optical amplifier (SOA). By using an interferometric modulation, the transmitter can dynamically control the chirp in the resulting modulated signal over the wide tuning range of the laser.Type: GrantFiled: July 30, 2004Date of Patent: December 15, 2009Assignee: JDS Uniphase CorporationInventors: Gregory A.

Patent number: 7310363Abstract: A semiconductor tunable laser (10) and an interferometer (12) coupled to the tunable laser (10) are monolithically fabricated in a semiconductor heterostructure. The laser also comprises a buried ridge stripe waveguide laser. The interferometer (12) has a semiconductor optical amplifier (38) coupled in each arm. A cross-gain semiconductor optical amplifier converter is coupled to the interferometer (12). The semiconductor optical amplifier (38) coupled in each arm is biased so that an optical path length difference between the two arms is in antiphase which results in destructive interference. The output of the tunable laser (10) is coupled to a coupler. A semiconductor optical amplifier (38) is used as a gain controller for the semiconductor optical amplifiers in the interferometer (12) to allow wavelength conversion over a larger range of input signal powers.Type: GrantFiled: September 28, 2000Date of Patent: December 18, 2007Assignee: The Regents of the University of CaliforniaInventors: Thomas Gordon Beck Mason, Gregory Fish, Daniel J Blumenthal
