1. A method to fabricate a vertical cavity surface emitting laser (VCSEL) capable of optical emission, the method comprising:
forming a first distributed Bragg reflector (DBR) on a substrate;
forming, on the first DBR, an optical layer having an active region by:
forming a first portion of the optical layer on the first DBR;
forming a plurality of dimensioned features on a surface of the first portion, at least one of the dimensioned features being different from the other dimensioned features; and
forming a second portion of the optical layer by filling the plurality of dimensioned features on the surface of the first portion; and
forming a second DBR on the optical layer,
wherein forming the second portion of the optical layer includes forming at least one layer of the second DBR on the plurality of dimensioned features, and
wherein the at least one layer of the second DBR comprises the second portion of the optical layer.
