Switchable thermal waveguides in GaAs based devices Open
The modulation of light within microscopic devices is the key to designing versatile and powerful photonic integrated circuits (PICs). Contemporary techniques are able to generate a wide range of waveguiding and waveforming elements. They …

Precise prediction of optical behaviour of mechanically stressed edge emitting GaAs devices Open
The presence of a thermally annealed metallization layer on top of a GaAs slab waveguide proofed to be of strong impact on the optical device behavior. Induced by the stress on the chip the elasto-optical effect imprinted a strong variatio…
