Electro-activation and electro-morphing of photorefractive funnel waveguides

Electro-optic and electro-absorption characterization of InAs quantum dot waveguides.

Optical properties of multilayer InAs quantum dot waveguides, grown by molecular beam epitaxy, have been studied under applied electric field. Fabry-Perot measurements at 1515 nm on InAs/GaAs quantum dot structures yield a significantly enhanced linear electro-optic efficiency compared to bulk GaAs. Electro-absorption measurements at 1300 nm showed increased absorption with applied field accomp...

Development of Electro-optical Pcbs with Polymer Waveguides

We have developed technologies to embedded high-speed polymer optical interconnects on printed circuit boards for 850 nm applications. In this paper, we show results of fabricating optical-PCBs on a production scale panels in a modern HDI-PCB (high-density interconnect-PCB) process environment. Impacts on board design and manufacturing were studied with the developed optical technology verifier...

Electro-Optic Coefficient Enhancement in Poled LiNbO3 Waveguides

Lithium niobate crystals (LN) show a significant electro-optic (EO) response which contributes to the fabrication of low-voltage operation, high speed integrated optical modulators routinely used in optical telecommunication and integrated optics [1]. A UV laser direct writing method for the fabrication of optical channel waveguides has been proposed and characterized recently [2–4]. Here we re...

Enhanced electro-optic phase shifts in suspended waveguides.

We demonstrate enhanced electro-optic phase shifts in suspended InGaAs/InGaAsP quantum well waveguides compared to attached waveguides. The enhancement stems from an improved overlap between the optical mode and the multiple quantum well layers in thin waveguides when the semiconductor material beneath the waveguide is selectively etched. The measured voltage length product is 0.41 V-cm and the...
