Gain medium providing laser and amplifier functionality to optical device

摘要

An optical device includes a gain medium on a substrate. The device also includes one or more laser cavities and an amplifier on the substrate. The one or more laser cavities each guides a light signal through a different region of the gain medium such that each of the light signals is amplified within the gain medium. The amplifier guides an amplified light signal through the gain medium such that the amplified light signal is amplified in the gain medium.

主权项

1. An optical device, comprising:
a continuous gain medium located on a substrate; one or more laser cavities on the substrate, each laser cavity guiding a different light signal through the gain medium, each of the laser cavities outputting a laser light signal; an amplifier on the substrate, the amplifier guiding an amplified light signal through the gain medium; and waveguides on the substrate, the waveguides receiving light from the one or more laser signals after the received light has exited from the gain medium,
the waveguides guide the received light to the amplifier.
