A tunable light source with a liquid-crystal Fabry Perot interferometer (LC-FPI) tuning element has been constructed that emits a laser beam with a tuning range of 41 nm. Incorporating an MQW laser diode with a phase control (PC) section enables the selection of almost all external modes. Stable single-mode emission is obtained for the region, except where the slope of the lasing wavelength versus applied voltage to the liquid crystal is quite large.
