Abstract: Described are various configurations of integrated wavelength lockers including asymmetric Mach-Zehnder interferometers (AMZIs) and associated detectors. Various embodiments provide improved wavelength-locking accuracy by using an active tuning element in the AMZI to achieve an operational position with high locking sensitivity, a coherent receiver to reduce the frequency-dependence of the locking sensitivity, and/or a temperature sensor and/or strain gauge to computationally correct for the effect of temperature or strain changes.

Abstract: A device, such as an electroabsorption modulator, can modulate a light intensity by controllably absorbing a selectable fraction of the light. The device can include a substrate. A waveguide positioned on the substrate can guide light. An active region positioned on the waveguide can receive guided light from the waveguide, absorb a fraction of the received light, and return a complementary fraction of the received light to the waveguide. Such absorption produces heat, mostly at an input portion of the active region. The input portion of the active region can be thermally coupled to the substrate, which can dissipate heat from the input portion, and can help avoid thermal runaway of the device. The active region can be thermally isolated from the substrate away from the input portion, which can maintain a relatively low thermal mass for the active region, and can increase efficiency when heating the active region.

Abstract: Described herein are methods, systems, and apparatuses to utilize a semiconductor optical amplifier (SOA) comprising a silicon layer including a silicon waveguide, a non-silicon layer disposed on the silicon layer and including a non-silicon waveguide, first and second mode transition region comprising tapers in the silicon waveguide and/or the non-silicon waveguide for exchanging light between the waveguide, and a plurality of regions disposed between the first and second mode transition regions comprising different cross-sectional areas of the silicon waveguide and the non-silicon waveguide such that confinement factors for the non-silicon waveguide in each of the plurality of regions differ.
