Abstract
Examples herein relate to optical systems. In particular, implementations herein relate to an optical system including an optical transmitter configured to transmit optical signals. The optical transmitter includes a first optical source and a second optical source coupled to the first optical source and injection seeded by the first optical source. The optical transmitter further includes an output coupler, the second optical source coupled to the optical coupler via an output waveguide and configured to emit light having multiple different wavelengths through the output waveguide. In some implementations, the second optical source is self-injection seeded.
Claims9
An optical transmitter configured to transmit optical signals, the optical transmitter comprising:
- a first optical source;
- a second optical source coupled to the first optical source and injection seeded to the first optical source;
- an optical coupler, the second optical source coupled to the optical coupler via an output waveguide and configured to emit light having multiple different wavelengths through the output waveguide to the output coupler;
- and
- an optical tap, wherein light from the first optical source is injected into the second optical source via the optical tap.
