We present an approach for manipulating light in an optical micro-structured photonic crystal fiber by displacing and positioning micro-fluids along the air-holes of the fiber.

We demonstrate for the first time that an electrically tunable chirped fiber Bragg grating can be used to trim the dispersion in a 160 Gb/s TDM system with a RZ duty cycle of 30%.

We present a multichannel tunable dispersion compensator based on multicavity all-pass etalons that is capable of operation at 40Gb/s.

We demonstrate for the first time that an electrically tunable chirped fiber Bragg grating can be used to trim the dispersion in a 160 Gb/s TDM system with a RZ duty cycle of 30%.

We demonstrate a compact silica-waveguide 10-Gb/s dispersion compensator with single-knob tuning that works with uncontrolled wavelength transmitters by automatically locking to the signal waveleng

Planar waveguide allpass filters providing a large continuous dispersion tuning range (±2000 ps/nm) and system performance results for 10 Gb/s NRZ signals will be discussed

We demonstrate a novel tunable dispersion compensator that utilizes higher order mode fibers and switchable, fiber gratings.

A simple way to improve the output power of singlemode tunable VCSELs is demonstrated. It is based on a master oscillator power amplifier (MOPA)-like embodiment of a fibre-VCSEL.

Highly compact dual-mode semiconductor laser sources get more and more attention in different application fields such as radar, security and personal communication systems.

We describe the generation of 350 fs pulses tunable between 2.3 and 5.5microns by seeded optical parametric amplification.
