Abstract
In some implementations, an optical device (e.g., a monolithic master oscillator power amplifier (MOPA) diode) may include a first facet, one or more gratings, an amplifier structure terminated with a second facet, and an oscillator array that includes multiple singlemode oscillators coupled to the first facet and to the one or more gratings. In some implementations, the multiple singlemode oscillators may be configured to generate multiple seed beams and to transmit the multiple seed beams into the amplifier structure through the one or more gratings.
Claims20
An optical assembly, comprising:
- an optical device that includes multiple grating-locked single-mode oscillators configured to transmit multiple seed beams having different wavelengths into a shared amplifier structure,
- wherein the multiple seed beams expand within the shared amplifier structure to form chirped light that is emitted by the optical device;
- a dispersive element in an optical path between a laser diode and an optical fiber;
- and
- one or more collimator lenses coupling the chirped light to the dispersive element,
- wherein the multiple seed beams that have the different wavelengths impinge upon the dispersive element at different incidence angles, and
- wherein the dispersive element is arranged to transmit the multiple seed beams at respective angles that cause the multiple seed beams to overlap in an output beam that enters the optical fiber.
