Abstract: A laser structure, including: a dielectric matrix formed of a first material; a laser source formed within the dielectric matrix and formed of a semiconductor material; and a plurality of side confining features formed within the dielectric matrix and extending parallel to and along a length of the laser source. The plurality of side confining features are formed of the semiconductor material.

Abstract: Embodiments of the disclosure provide a demultiplexer for processing a multiplexed optical input. The demultiplexer may include a plurality of Mach-Zehnder Interferometric (MZI) stages for converting the multiplexed optical input into a plurality of component optical signals. Each of the plurality of component optical signals corresponds to a respective wavelength-space component of the multiplexed optical input. A plurality of bandpass filters, each having a respective wavelength passband, may receive one of the plurality of component optical signals. The plurality of bandpass filters generates a plurality of demultiplexed optical signals based on the plurality of component optical signals.
