A photonic band gap fiber has been generated by incorporating a high index fluid into a sol-gel derived microstructured fiber.

We report the development of a tunable photonic crystal coupled-cavity laser diode based on InP.

We present a tunable photonic crystal laser with an integrated wavelength monitor.

We demonstrate tunable semiconductor lasers based on three coupled photonic crystal sections, that allows up to 18 nm tuning range with a side-mode suppression ratio greater than 35 dB.

We discuss a technique that allows for flexible synthesis of square QAM constellations via the direct modulation of tunable, injection locked, semiconductor lasers.

In-homogeneously broadened quantum dot gain material is butt-coupled to a dual-cavity silicon photonic integrated circuit.

Tunable optical filters have applications in wavelength division multiplexing, optical sensing, and fiber lasers.

Tunable, stimulated emission of radiation is achieved in Al sub x Ga sub (1-x) As/GaAs double heterostructures, in which the wave-quiding GaAs region consists of a delta-doped doping superlattice.

We introduce a platform based on passive and electro-optic polymers, and present a serial 100G transmitter with 22-nm tunability.

Laser diodes with optical feedback can exhibit periodic intensity oscillations at or near the relaxation-oscillation frequency.
