Abstract: In the examples provided herein, an apparatus has a first substrate upon which one or more first filters have been fabricated on a first surface of the first substrate. The apparatus also has a second substrate upon which one or more second filters have been fabricated on a second surface of the second substrate, wherein the one or more first filters and the one or more second filters each transmit a different band of wavelengths. Additionally, the apparatus has a bonding material that bonds the first substrate to the second substrate.

Abstract: Examples of the present disclosure include a tunable laser comprising an optical coupler to couple light between a first laser cavity and a second laser cavity. The first laser cavity may extending between the optical coupler and a first reflector and include a first gain section. The second laser cavity may extend between the optical coupler and a second reflector and including a second gain section. At least one of the first laser cavity and the second laser cavity is tunable.

Abstract: A vertical-cavity surface-emitting laser (VCSEL) includes 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 the VCSEL through the substrate. The VCSEL lases in a single transverse mode.

Abstract: Examples include generating a signal using a modulatable source. The signal may be propagated using a multi-mode fiber to receive the signal from the modulatable source. The fiber has a diameter d and a far-field divergence angle associated with the propagated signal that corresponds to a product of the diameter (d) and the far-field divergence angle. The product may be substantially between 1 micron radian and 4 micron radian. In some examples, the propagated signal may be received at a receiver from the multi-mode fiber.
