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.

A monolithic optical device, comprising:
- a first facet;
- one or more front gratings;
- an amplifier structure terminated with a second facet;
- and
- an oscillator array coupled to the first facet and to the one or more front gratings,
- wherein the oscillator array includes multiple singlemode oscillators configured to generate multiple seed beams, and
- wherein the multiple singlemode oscillators are coupled into the amplifier structure such that the multiple singlemode oscillators transmit the multiple seed beams through the one or more front gratings and into the amplifier structure.
A package structure, comprising:
- at least one row of multiple optical devices staggered in height, wherein the multiple optical devices each include:
- an amplifier structure terminated with an emission facet;
