Highly linear optical phase modulators are attractive for many applications including laser gyroscopes, multi-wavelength laser sowes, beam steering, and photonic arbitmy waveform generators [l]. Although commonly used phase modulators based on lithium niobate have an inherent high linearity, they cannot provide the degree of integration required for… (More)
Spectral interferometry is used to measure the dispersion of a quantum dot semiconductor optical amplifier under various injection current values in the wavelength range of 1200 to 1340 nm, spanning ground and first excited state.
An optical pulse injection locking technique is employed to generate shorter pulses from a passively modelocked quantum dot laser. The optical pulse injection locking enables the coherent addition of phaselocked longitudinal mode groups from two separate modelocked lasers without the use of stabilisation control loops, thus increasing the spectral bandwidth… (More)
A hybrid mode-locked fiber laser was built by using a PDMS/SWCNTs film as a saturable absorber. The system allows for a high repetition rate of 4 GHz, while achieving pulse widths of 730 fs.
