Abstract
Various embodiments of an arrangement for generating fast wavelength-switched optical signal are described herein. In some embodiments, the arrangement can be integrated with lasers, optical waveguides, optical splitters and gates to form a fast wavelength switched monolithic optical source. In some embodiments, an optical modulator is incorporated into the arrangement to form a fast wavelength switched optical transmitter.
Claims7
A fast wavelength switched optical source comprising:
- At least one monolithic substrate
- An in-plane semiconductor laser monolithically integrated with the substrate, said laser being fixed wavelength or tunable, and configured to emit optical radiation from the output reflector along an optical axis
- A second in-plane semiconductor laser monolithically integrated with the substrate, said laser being fixed wavelength or tunable, and configured to emit optical radiation from the output reflector along an optical axis
- An optical combiner element monolithically integrated with the substrate, with at least 2 input ports and at least 1 output port, where at least 2 input ports are connected to the first and second laser, and where the signal from the first and the second laser are guided to on one or more of the common output ports
