The growth began with aluminum nitride (AlN) seed and buffer layers. This was followed by a two-period system of a 400nm GaN layer (~400nm) and a low-temperature AlN layer (~10nm) to create compressive stress for the final 800nm GaN layer. The final layer consisted of 150nm of undoped GaN, with the remain-der doped with Si or Ge.

PORT: A PIEZOELECTRIC OPTICAL RESONANCE TUNER

This abstract presents an aluminum nitride (AlN) piezoelectric actuator for tuning optical resonance modes of silicon nitride photonic resonators. The AlN actuator is fabricated on top of a thick silicon dioxide cladding that encapsulates the nitride resonator and waveguide. The PORT is defined by undercutting the cladding layer with a

Optical properties and stress of ion-assisted aluminum ...

The optical properties and stress in thin films of aluminum nitride have been studied as a function of ion energy and the ion-to-vapor arrival ratio (Ji/Jv) for the N2+ ion-assisted deposition of aluminum. The ion energy was varied between 75 and 1000 eV. The refractive index was found to depend on the ion energy and flux. The highest index was 2.10 at 633 nm.
