1. An optical amplifier comprising:

  • a substrate;

    a first Distributed Bragg Reflector (DBR) stack arranged over the substrate, the first DBR stack including a plurality of mirror pairs each having a first layer and a second layer, wherein a duty cycle of each mirror pair is selected such that a phase shift of the first layer is less than or greater than 90 degrees;

    an active region formed on the first DBR stack, wherein the duty cycle of each mirror pair is selected such that an amplifier mode does not couple to the first DBR stack; and

    a second DBR stack formed on the active region.
