摘要:
A monolithic vertical optical cavity device (100) has a bottom Distributed Bragg Reflector (DBR), a quantum well (QW) region consisting of at least one active layer grown on top of the bottom DBR by using a Selective Area Epitaxy (SAE) mask such that the active layer or layers exhibit a variation in at least one physical parameter in a horizontal plane perpendicular to the vertical direction and a top DBR deposited on top of the QW region (70). The device has a variable Fabry-Perot distance (82) defined along the vertical direction between the bottom DBR (50) and the top DBR (76) and a variable physical parameter of the active layer.
