Abstract
Femtosecond laser fabrication of optical waveguides in bulk silica glass is extended to integrated optical waveplates. Polarization retardation was controlled by laser exposure, providing for trimming of waveguide birefringence between 10-5 and 10-4. © OSA/ CLEO 2011.

Abstract
An integrated optical refractometer based on multimode interference, with sensitivity enhancement due to sub-micrometer axial features, is demonstrated with experimental sensitivity as high as 3200 nm/RIU and resolution limits on the order of 5 ppm. © OSA/CLEO 2011.

Abstract
High strength, first order Bragg Grating Waveguides are inscribed in the core and cladding of optical fibers using oil immersion femtosecond direct laser-writing. A laser-induced birefringence of 2.05×10-4 was inferred from polarization split Bragg resonances. ©OSA/ CLEO 2011.
