Spatial Mode Matching Efficiencies for Heterodyned GaAlAs Semiconductor Lasers
نویسنده
چکیده
High spatial mode matching efficiencies are experimentally demonstrated when open-loop frequency-stabilized GaAlAs semiconductor lasers are heterodyned on silicon p-i-n detectors. Repeatable values of 75 percent are obtained using two independent lasers. The mode matching efficiency increases to 90 percent when a single modulated laser is self-heterodyned using an unequal path length MachZehnder interferometer. Experimental data is shown to match closely with theoretical predictions.

Confocal unstable-resonator semiconductor laser.
GaAs/GaAlAs heterostructure lasers with a monolithic confocal unstable resonator were demonstrated. The curved mirrors satisfying the confocal condition were fabricated by etching. Close to threshold, the lasers operate in a single lateral mode with a nearly collimated output beam. A single-lobe far-field intensity distribution as narrow as 1.9 degrees full width at half maximum was measured.
متن کاملInfluence of external optical feedback on the alpha factor of semiconductor lasers.
This Letter presents the results revealing the influence of external optical feedback (EOF) on the alpha factor, or the linewidth enhancement factor, of semiconductor lasers operating on single mode. First, a method is proposed for the measurement of the alpha over a wide range of optical feedback level, which provides an effective way for investigating the dependence of the alpha on laser oper...

متن کاملSingle-mode diode laser with a large frequency-scanning range based on weak grating feedback.
A single-mode GaAlAs diode laser with over 90% output-coupling power and a large frequency-scanning range is reported. Based on grating feedback in the Littrow configuration, it is demonstrated that, with weak feedback (1.5 × 10(-3) in this experiment), over a 7.5-GHz continuous tuning range can be achieved around tuning gaps of free-running operation. A frequency self-locking effect is also de...
