Abstract: Described are various configurations of reduced crosstalk optical switches. Various embodiments can reduce or entirely eliminate crosstalk using a coupler that has a power-splitting ratio that compensates for amplitude imbalance caused by phase modulator attenuation. Some embodiments implement a plurality of phase modulators and couplers as part of a dilated switch network to increase overall bandwidth and further reduce potential for crosstalk.

Abstract: An optical system can lock a wavelength of a tunable laser to a specified wavelength of a temperature-insensitive spectral profile of a spectral filter. In some examples, the spectral filter, such as a Fabry-Perot filter, can have a temperature-insensitive peak wavelength and increasing attenuation at wavelengths away from the peak wavelength. The spectral filter can spectrally filter the laser light to form filtered laser light. A detector can detect at least a fraction of the filtered laser light. Circuitry coupled to the detector and the laser can tune the tunable laser to set a signal from the detector to a specified value corresponding to a specified wavelength in the spectral profile, and thereby adjust the selectable wavelength of the tunable laser to match the specified wavelength. In some examples, the optical system can include a polarization rotator, and can use polarization to separate incident light from return light.

Abstract: The wavelength response of an arrayed waveguide grating can be tuned, in accordance with various embodiments, using a beam sweeper including one or more heaters to shift a lateral position of light focused by the beam sweeper at an interface of the beam sweeper with an input free propagation region of the arrayed waveguide grating.

Abstract: Embodiments describe high-efficiency optical waveguide transitions—i.e., creating heterogeneous transitions between Si and III-V semiconductor regions or devices with minimal reflections. This is advantageous for III-V device performance, e.g. for an on-chip lasers achieving lower relative intensity noise (RIN) and lower phase noise by avoiding reflections, higher gain and reduced gain-ripple from an semiconductor optical amplifier (SOA) by avoiding internal reflections in the SOA. Furthermore, in some embodiments, generated photocurrent can be used as a monitor signal for control purposes, thereby avoiding the use of separate tap-monitor photodetectors, which provide additional link loss.
Abstract translation: 实施例描述了高效光波导转换，即，在具有最小反射的Si和III-V半导体区域或器件之间产生异质过渡。 这对于III-V器件的性能是有利的，例如 通过避免SOA中的内部反射，通过避免半导体光放大器（SOA）的反射，更高的增益和更小的增益波动来实现较低相对强度噪声（RIN）和较低相位噪声的片上激光器。 此外，在一些实施例中，产生的光电流可以用作监控信号用于控制目的，从而避免使用提供附加链路损耗的单独的抽头监视器光电探测器。

Abstract: Embodiments of the invention describe photonic integrated circuits (PICs) for accomplishing polarization splitting and rotation. Embodiments of the invention include a first waveguide to receive light comprising orthogonally polarized transverse electric (TE) and transverse magnetic (TM) modes, and a second waveguide disposed below the first waveguide and comprising a reverse taper-shaped side to adiabatically receive one of the polarization modes (e.g., the TE mode) of the received light from the first waveguide. Said horizontal offset between the first and the reverse taper-shaped side of the second waveguide comprises an offset such that, for example, the TM mode of the received light is rotated to a TE mode in the first waveguide. The above described offsets and taper shaped structures may also be used in an optical combiner.

Abstract: Described herein are methods, systems, and apparatuses to utilize an electro-optic modulator including one or more heating elements. The modulator can utilize one or more heating elements to control an absorption or phase shift of the modulated optical signal. At least the active region of the modulator and the one or more heating elements of the modulator are included in a thermal isolation region comprising a low thermal conductivity to thermally isolate the active region and the one or more heating elements from a substrate of the PIC.
