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.

Abstract
We experimentally demonstrate the first integrated temporal Fourier transformer based on a linearly chirped Bragg grating waveguide written in silica glass with a femtosecond laser. The operation is based on mapping the energy spectrum of the input optical signal to the output temporal waveform by making use of first-order chromatic dispersion. The device operates in reflection, has a bandwidth of 10 nm, and can be used for incident temporal waveforms as long as 20 ps. Experimental results, obtained through both temporal oscilloscope traces and Fourier transform spectral interferometry, display a successful Fourier transformation of in-phase and out-of-phase pairs of input optical pulses, and demonstrate the correct functionality of the device for both amplitude and phase of the temporal output.
