A liénard oscillator resonant tunnelling diode-laser diode hybrid integrated circuit: model and experiment [PDF]
We report on a hybrid optoelectronic integrated circuit based on a resonant tunnelling diode driving an optical communications laser diode. This circuit can act as a voltage controlled oscillator with optical and electrical outputs.

Optical bistability in diode-laser amplifiers and injection-locked laser diodes
Static and dynamic properties of dispersive optical bistability (OB) in semiconductor lasers biased from below to above threshold have been investigated theoretically. The OB result is found to be varied continuously from below to above threshold with its maximum value located just above threshold; this result has been verified experimentally.

Intra-cavity frequency doubling of an electrically pumped edge-emitting 980 nm laser diode with PPLN [PDF]
The growing trend for laser-based projection displays makes intra-cavity frequency doubling (ICFD) of electrically and optically surface emitting diode lasers in the near IR region become more interesting [1-3].

Characterization of tapered diode laser bars for the use in high power diode laser systems
S.56-64For further development in beam quality of high power diode laser systems a new type of diode laser bars has been realized recently. Compared to commercially available broad area diode laser bars the lateral design of tapered diode laser bars ...

Self-mixing interference effects in tunable diode laser absorption spectroscopy [PDF]
We report the effects of self-mixing interference on gas detection using tunable diode laser spectroscopy. For very weak feedback, the laser diode output intensity gains a sinusoidal modulation analogous to that caused by low finesse etalons in the ...
