摘要： In one example, an optical device may include a waveguide having a core index of refraction that decreases along a length of the waveguide and an edge index of refraction of the waveguide that is constant along the length of the waveguide. The central rays of the optical signals travelling through the waveguide may be refracted towards higher radii while the outer rays propagate unaffected. The optical device may decrease dispersion of the optical signals travelling through an optical fiber.

摘要： In an example embodiment, an N-channel WDM OSA includes active optical devices coupled to a carrier, an optical block, and a MUX or a DEMUX. The optical block may be positioned above the active optical devices and coupled to the carrier. The optical block may include a bottom with lenses formed in the bottom that are aligned with the active optical devices; a first side that extends up from the bottom; a second side that extends up from the bottom and is opposite the first side; a port that extends forward from the bottom and the first and second sides; and an optical block cavity defined by the bottom and the first and second sides that extends rearward from the port. The MUX or DEMUX may be positioned in the optical block cavity in an optical path between the port of the optical block and the active optical devices.

摘要： In one example, a laser assembly may include a substrate, a lens array, and a laser array. The lens array may be positioned on a first side of the substrate. The laser array may be positioned on a second side of the substrate opposite the first side. Lasers of the laser array may be oriented to generate optical signals through the substrate to corresponding lenses of the lens array. The lens array may include at least one concave lens and at least one convex lens. The concave and convex lenses may map the irradiance of the lasers to a common target irradiance profile, resulting in an alignment tolerant laser assembly.
