Abstract: Optical modulators and modulation techniques for advanced optical modulation formats are described. An optical modulator may include two optical modulators in parallel optical paths, and optical powers in the two paths may be unequal. Polarization in the two paths may be orthogonal, and modulated outputs from each path may be combined to produce multilevel modulation formats.

Abstract: An optical isolator for suppressing back reflections from a downstream optical system is described. The optical isolator includes a plurality of optical paths between a splitter and a combiner. One or more of the optical paths include two phase modulators that are driven by oscillating signals having predefined phase relationships. At least one bypass optical path does not include two phase modulators driven by oscillating signals. Amplitude and phase of an optical signal traversing the bypass optical path may be tuned to further suppress residual reflections from a downstream optical system.

Abstract: Disclosed herein are methods, structures, and devices for a silicon carrier-depletion based modulator with enhanced doping in at least part of slab regions between waveguide core and contact areas. Compared to prior designs, this modulator exhibits lower optical absorption loss and better modulation bandwidth without sacrificing the modulation efficiency when operating at comparable bandwidth settings.

Abstract: A tunable laser that includes an array of parallel optical amplifiers is described. The laser may also include an intracavity N×M coupler that couples power between a cavity mirror and the array of parallel optical amplifiers. Phase adjusters in optical paths between the N×M coupler and the optical amplifiers can be used to adjust an amount of power output from M−1 ports of the N×M coupler. A tunable wavelength filter is incorporated in the laser cavity to select a lasing wavelength.

Abstract: Disclosed herein are techniques, methods, structures and apparatus that provide a laser monolithically integrated in a silicon photonic integrated circuit (PIC) that is suitable for high-performance coherent fiber-optic telecommunications and other applications. Among the features of a laser according to the present disclosure, and in particular a hybrid InGaAsP/Si laser, is an integrated Si isolator to protect the laser from back reflections; optical, rather than electrical pumping; and coupling the optical pump using an InGaAsP grating coupler that acts simultaneously as a WDM coupler and laser mirror.

Abstract: A method for fabricating a grating coupler having a bottom mirror in a semiconductor wafer including etching a trench from a top surface of a wafer and around a grating coupler formed in the wafer; etching a void underneath the grating coupler; etching a via into the void from the backside of the wafer; and depositing a mirror on the bottom of the grating coupler. Alternatively, additional oxide may be deposited on the bottom of the grating coupler prior to the deposition of the mirror such that a desirable oxide thickness on the bottom is achieved.
