Suppression of mode-hop-induced optical signal deterioration in an external-cavity-diode laser with a fiber-Bragg grating for uncooled wavelength-division-multiplexing applications.
This paper reports on an external-cavity-diode laser (ECDL) employing a fiber Bragg grating, which was newly designed for WDM applications without temperature control. An optical signal waveform generated by the novel ECDL when the longitudinal lasing mode hopped was observed directly for the first time. It is confirmed that optical signal degradation caused by mode hopping can be suppressed effectively.
