Abstract:
A monolithic vertical optical cavity extending along a vertical direction, comprising:a first bottom Distributed Bragg Reflector including a plurality of bottom reflectors;a second bottom Distributed Bragg Reflector including a plurality of bottom reflectors grown on the first bottom Distributed Bragg Reflector using a first Selective Area Epitaxy mask, the second Bottom Distributed Bragg Reflector including at least one active layer having at least one physical parameter exhibiting a variation in a horizontal plane;a Quantum Well region grown on top of the second bottom Distributed Bragg Reflector using the first Selective Area Epitaxy mask, the Quantum Well region including at least one active layer having at least one physical parameter exhibiting a variation in the horizontal plane;a top Distributed Bragg Reflector deposited on top of the Quantum Well region and having a plurality of top reflectors;wherein a Fabry-Perot distance defined along the vertical direction between the first bottom Distributed Bragg Reflector and the top Distributed Bragg Reflector varies in the horizontal plane.
