Abstract: In example implementations, an apparatus is provided. The apparatus includes an optical transmission component and an optical reception component. The optical transmission component includes a plurality of lasers and a transmit filter. The plurality of lasers each emit a different wavelength of light. The transmit filter includes a plurality of different regions that correspond to one of the different wavelengths of light emitted by the plurality of lasers. The optical reception component includes a plurality of photodiodes and a complementary reverse order (CRO) filter. The CRO filter includes a same plurality of different regions as the transmit filter in a reverse order.

Abstract: Techniques related to optical devices including a high contrast grating (HCG) lens are described herein. In an example, an optical device includes a transparent substrate. A laser emitter or detector at a first side of the transparent substrate to emit or detect a laser light transmitted via the transparent substrate. A HCG lens is at a second side of the transparent substrate to transmit and refract the laser light.

Abstract: A vertical-cavity surface-emitting laser (VCSEL) includes a first reflector having a first reflectivity; a second reflector having a second reflectivity, where the second reflectivity is less than the first reflectivity; a gain region between the first and second reflectors; and a substrate having a first surface and a second surface, where the first surface is coupled to the second reflector, and where the second surface is formed into a lens to act upon light emitted by the VCSEL through the substrate. The VCSEL lases in a single transverse mode.

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 apparatus (2) can comprise an optical slab (4) comprising a rigid substrate of substantially transmissive material. The apparatus (2) can also comprise a WDM multiplexer (6) to receive and combine a plurality of optical signals (14, 16 and 20) at different wavelengths to form a combined optical signal (24) in the optical slab (4) having an aggregate power. The apparatus can further comprise a broadcaster (28) to distribute the combined optical signal (24) from the optical slab (4) to each of a plurality of different optical receivers (30, 32 and 34) with a fraction of the aggregate power of the combined optical signal (24).
