摘要： A transmission circuit includes an array of subarrays of emitters with quasi-periodic spacing. A first subarray of emitters emits a source signal, and a second subarray of emitters emits the source signal. The first and second subarrays are separated by a subarray spacing that quasi-periodic, wherein the spacing between different subarrays is different. The quasi-periodic subarray spacing is to cause constructive interference of a main lobe of the emissions from the subarrays, and to cause non-constructive interference of sidelobes of the emissions. The spacing between emitters in the subarrays can vary from one subarray to another.

摘要： 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.

摘要： A vertical total internal reflection (TIR) mirror and fabrication thereof is made by creating a re-entrant profile using crystallographic silicon etching. Starting with an SOI wafer, a deep silicon etch is used to expose the buried oxide layer, which is then wet-etched (in HF), opening the bottom surface of the Si device layer. This bottom silicon surface is then exposed so that in a crystallographic etch, the resulting shape is a re-entrant trapezoid with facets These facets can be used in conjunction with planar silicon waveguides to reflect the light upwards based on the TIR principle. Alternately, light can be coupled into the silicon waveguides from above the wafer for such purposes as wafer level testing.

摘要： Embodiments herein relate to a photonic integrated circuit (PIC) with an on-chip optical isolator. The PIC may comprise a laser, a waveguide coupled with the laser, and a closed loop resonator coupled to the laser through the waveguide. A magneto-optical (MO) layer is over and in contact with the waveguide and the closed loop resonator. The closed loop resonator may comprise a first polarization rotator (PR) and a second PR. A light from the laser in transverse electric (TE) mode through the waveguide is rotated in the first PR to a light in transverse magnetic (TM) mode, and the light in TM mode is rotated in the second PR to light in TE mode. The isolator may further comprise a micro-heater over or along a side of the waveguide and separated from the closed loop resonator; and a feedback control loop connected to the closed loop resonator and the micro-heater.
