Abstract: In the examples provided herein, a data center transmission system includes a VCSEL (vertical-cavity surface-emitting laser) that lases in a single spatial mode with a side mode suppression ratio of at least 25 dB, where the VCSEL is formed on a substrate and lases at a wavelength transparent to the substrate, and further where an output of the VCSEL exits through the substrate. Also, the VCSEL is directly modulated. The system further includes an optical fiber having a first end to receive the output of the VCSEL for propagation along the optical fiber. The optical fiber supports a single spatial mode without supporting higher order spatial modes over a range of wavelengths between 1260 nm and 1360 nm. The system also includes a receiver to receive the directly modulated output of the VCSEL after propagation through the optical fiber.

Abstract: Examples herein relate to polarization diversity optical interface assemblies including a single mode optical fiber and first and second grating couplers disposed on a substrate. The first and second grating couplers are coupled to first and second waveguides, respectively. The assemblies further includes an optical connector to couple light between the single mode optical fiber and each of the first and second grating couplers. The optical connector includes a ferrule and a walk-off crystal. The ferrule is coupled to a portion of the single mode optical fiber. The walk-off crystal is configured to spatially separate the light into first and second orthogonal polarization modes prior to passing through the respective first and second grating couplers and/or combine the first and second polarization modes of the light prior to passing through the single mode optical fiber.

Abstract: An example device in accordance with an aspect of the present disclosure includes a slab to transmit light, and a plurality of lenses and filters disposed on first and second surfaces of the slab. The lenses include an anti-reflective coating on at least one of the plurality of lenses at an end of the slab to couple light through the anti-reflective coating, and a reflective coating disposed on remaining ones of the plurality of lenses to cause the lenses to reflect light. The filters are offset from the lenses to form an optical zig-zag.

Abstract: A high contrast grating optical modulation includes an optical modulator at a front surface of a substrate to modulate received light. The high contrast grating optical modulation further includes a high contrast grating (HCG) lens adjacent to a back surface of the substrate opposite to the front surface to focus incident light onto the optical modulator. The substrate is transparent to operational wavelengths of the focused incident light and the modulated light.
