Abstract: In the examples provided herein, a system has a plurality of arrayed waveguide gratings (AWG) having a plurality of input ports and a plurality of output ports. A signal within a given wavelength channel transmitted to one of the input ports of a given AWG is routed to one of the output ports of the given AWG based on a signal wavelength. The system also has a plurality of nodes, with each node comprising a set of components for each AWG that the node is coupled to. Each set of components comprises a plurality of optical transmitters, where each optical transmitter is tunable over multiple wavelength channels within a different wavelength band; a band multiplexer to multiplex the multiple wavelength channels within each different wavelength band; and a first output fiber to couple an output of the band multiplexer to one of the input ports of a first AWG.

Abstract: An apparatus includes a first and second VCSEL, each with an integrated lens. The VCSELs emit a first light beam having first optical modes at first wavelengths and a second light beam having second optical modes at second wavelengths. The apparatus also has an optical block with a first and second surface, a mirror coupled to the second surface, and a wavelength-selective filter coupled to the first surface. The first integrated lens mode matches the first beam to the optical block, and the second integrated lens mode matches the second beam to the optical block such that the first beam and second beam each have substantially a beam waist with a beam waist dimension at the first and second input region, respectively. An exit beam that includes light from the first beam and the second beam is output from the second surface of the optical block.

Abstract: An example system may include a first vertical cavity surface emitting laser (VCSEL) that includes a first integrated polarization locking structure to produce a polarized optical data signal. The system may also comprise a second VCSEL that includes a second integrated polarization locking structure, the second integrated polarization locking structure orthogonal to the first integrated polarization locking structure, to produce an orthogonally polarized optical data signal. Lenses may be disposed on the substrate opposite the first VCSEL, to collimate the polarized optical data signal, and opposite the second VCSEL to collimate the orthogonally polarized optical data signal. A polarization division multiplexer may combine the first collimated polarized optical data signal and the second collimated orthogonally polarized optical data signal.

Abstract: Systems and methods are provided for a dual-side bi-directional optical multiplexing system includes a light receiving elements array receiving light from in an egress propagation direction from an optical fiber, arranged at a side of the optical fiber. The system also includes a light transmitting elements array emitting light in an ingress propagation direction into the optical fiber, and arranged at a second position to an opposing side of the optical fiber. The light receiving elements array and the light transmitting elements array are on dual-sides of the system with respect to the optical fiber. The system also includes bi-directional micro-optics interfacing with the optical fiber, and interfacing with the light transmitting elements array to direct light propagating in the ingress direction emitted from the light transmitting element array towards the optical fiber.

Abstract: An example Mach-Zehnder interferometer (MZI) is provided. The MZI includes a first waveguide arm and a second waveguide arm coupled to the first waveguide arm via a pair of optical couplers. In the proposed MZI, at least one of the first waveguide arm and the second waveguide arm includes a plurality of Bragg-grating segments and a phase-shifter segment formed between adjacent Bragg-grating segments of the plurality of Bragg-grating segments. The phase-shifter segment formed between adjacent Bragg-grating segments induces a predefined phase-shift in an optical signal propagating through respective at least one of the first waveguide arm and the second waveguide arm, resulting in increased linearity an optical transmission via the MZI.
