Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical coupler. In some embodiments, the device may include an optical waveguide to transmit light input from a light source. The optical waveguide may include a semiconductor layer, having a trench with one facet that comprises an edge formed under an approximately 45 degree angle and another facet formed substantially normal to the semiconductor layer. The edge may interface with another medium to form a mirror to receive inputted light and reflect received light substantially perpendicularly to propagate the received light. Other embodiments may be described and/or claimed.

Abstract: Techniques and mechanisms for a monolithic photonic integrated circuit (PIC) to provide spectrometry functionality. In an embodiment, the PIC comprises a photonic device, a first waveguide and a second waveguide, wherein one of the first waveguide and the second waveguide includes a released portion which is free to move relative to a substrate of the PIC. During a metering cycle to evaluate a material under test, control logic operates an actuator to successively configure a plurality of positions of the released portion relative to the photonic device. In another embodiment, light from the first waveguide is variously diffracted by a grating of the photonic device during the metering cycle, where portions of the light are directed into the second waveguide. Different wavelengths of light diffracted into the second waveguide may be successively detected, for different positions of the released portion, to determine spectrometric measurements over a range of wavelength.

Abstract: A portion of an optical waveguide extending laterally within a photonic integrated circuit (PIC) chip is at least partially freed from the substrate to allow physical displacement of a released waveguide end relative to the substrate and relative to an adjacent photonic device also fabricated in the substrate. The released waveguide end may be displaced to modulate interaction between the photonic device and an optical mode propagated by the waveguide. In embodiments where the photonic device is an optical coupler, employing for example an Echelle grating or arrayed waveguide grating (AWG), mode propagation through the coupler may be modulated via physical displacement of the released waveguide end. In one such embodiment, thermal sensitivity of an integrated optical wavelength division multiplexer (WDM) is reduced by displacing the released waveguide end relative to the coupler in a manner that counters a temperature dependence of the optical coupler.
Abstract translation: 在光子集成电路（PIC）芯片内侧向延伸的光波导的一部分至少部分地从衬底释放，以允许释放的波导端相对于衬底和相对于同样制造在衬底中的相邻光子器件的物理位移 。 释放的波导端可以被移位以调制光子器件与由波导传播的光学模式之间的相互作用。 在其中光子器件是光学耦合器的实施例中，例如采用阶梯光栅或阵列波导光栅（AWG），通过耦合器的模式传播可以通过释放的波导端的物理位移来调制。 在一个这样的实施例中，通过以抵消光耦合器的温度依赖性的方式相对于耦合器移位释放的波导端来减小集成光学波分多路复用器（WDM）的热灵敏度。

Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical device having a semiconductor layer to propagate light and a mirror disposed inside the semiconductor layer and having echelle grating reflective surface to substantially totally internally reflect the propagating light inputted by one or more input waveguides, to be received by one or more output waveguides. The waveguides may be disposed in the semiconductor layer under a determined angle relative to the mirror reflective surface. The determined angle may be equal to or greater than a total internal reflection angle corresponding to the interface, to provide substantially total internal reflection of light by the mirror. The mirror may be formed by an interface of the semiconductor layer comprising the mirror reflective surface and another medium filling the mirror, such as a dielectric. Other embodiments may be described and/or claimed.

Abstract: A solid state photonics circuit having a liquid crystal (LC) layer for beam steering. The LC layer can provide tuning of an array of waveguides by controlling the application of voltage to the liquid crystal. The application of voltage to the liquid crystal can be controlled to perform beam steering with the light signal based on different tuning in each of the waveguides of the array. The waveguides are disposed in a substrate having an oxide or other insulating layer with an opening. The opening in the oxide layer exposes a portion of a path of the array of waveguides. The waveguides are exposed to the liquid crystal through the oxide opening, which allows the voltage changes to the liquid crystal to tune the optical signals in the waveguides.
