Abstract: According to some implementations, an avalanche photodiode may include a photon absorbing layer to absorb photons of an optical beam and to provide a response. The avalanche photodiode may include a gain response layer to provide a gain to the response. The avalanche photodiode may include a bias control structure connected to the gain response layer to control an electric field in the photon absorbing layer and the gain response layer.

Abstract: An optical device may include a semiconductor laser chip to independently generate four laser beams at different wavelengths. Each laser beam, of the four laser beams, may be directed to a respective optical output of the optical device with a sub-micron level of tolerance of each laser beam relative to the respective optical outputs of the optical device, and each laser beam, of the four laser beams, may be associated with a different optical path from the semiconductor laser chip to the respective optical output of the optical device. The optical device may include a lens to receive each of the four laser beams. The lens may be positioned to direct each laser beam, of the four laser beams, toward the respective optical output of the optical device. The optical device may include an optical isolator to receive each of the four laser beams.
