Optics letters, 2006•opg.optica.orgA tunable single-mode laser is obtained by using a weakly coupled cavity structure involved
in a coaxially packaged Fabry–Perot laser diode. The cleaved end facet of the coupling fiber
becomes an optical reflector and forms an external cavity with a laser facet. The single-mode
oscillation condition is controlled and stabilized by tuning the operating temperature. The
tuning range is about 10 nm with the side-mode suppression ratio of more than 27 dB when
the temperature changes from 11.5° C to 25° C. Direct modulation characteristics were …

A tunable single-mode laser is obtained by using a weakly coupled cavity structure involved in a coaxially packaged Fabry–Perot laser diode. The cleaved end facet of the coupling fiber becomes an optical reflector and forms an external cavity with a laser facet. The single-mode oscillation condition is controlled and stabilized by tuning the operating temperature. The tuning range is about with the side-mode suppression ratio of more than when the temperature changes from to . Direct modulation characteristics were investigated, and our results show that a shorter external cavity can bear deeper modulation depth.
