Prospect and Current Status of Optical Communication Devices Based on Planar Lightwave Circuits

Active planar lightwave devices for optical signal processing

Time-domain numerical analysis of nonlinear propagation in Slow-Wave-Structures, focused on the interplay of enhanced third-order nonlinearity with chromatic dispersion has been carried on. In dependence on the operating conditions, a tunable optical oscillator/pulse train generator and an optical limiter have been designed. Morphological inspection and functional characterization at λ=1.5 μm o...

Topology optimization of planar Integrated Lightwave circuits

The following PhD thesis research has been conducted under the instruction of the Marie Curie Actions research centre at the Numerical Method Laboratory(LMN) program at the "POLITEHNICA" University of Bucharest (PUB), Faculty of Electrical Engineering, Romania. The Electrical Engineering program culminates with the PhD thesis project, which is closely guided by PUB faculty members associated wi...

MICROPHOTONIC DEVICES FOR COMPACT PLANAR LIGHTWAVE CIRCUITS AND SENSOR SYSTEMS by JAIME

SiON high-refractive-index waveguide and planar lightwave circuits

The rapidly growing optical communication market requires photonic components with ever-increasing functionality and complexity that can be fabricated reliably at low cost. Of the various approaches used to fabricate photonic components, those based on planar waveguides have achieved high performance and represent a promising path toward compact integration of optical functions. We present an o...

Optical Interconnect for 3D Integration of Ultra-Low Loss Planar Lightwave Circuits

We demonstrate the fabrication of a low loss broadband vertical coupler for use in the 3D integration of Si3N4 based planar waveguides. Coupling loss of 0.2 dB was achieved and interaction between layers investigated. OCIS codes: (230.0230) Optical Devices; (230.7390) Waveguides, planar; (230.4170) Multilayers.
