A near-IR tunable external-cavity laser that uses an electro-optic deflector and a reflection grating as a tunable filter is demonstrated. The deflector is an electronically reconfigurable nonpixelated nematic liquid-crystal device. By controlling the voltage applied to the electro-optic deflector, a tuning range of 12 nm and a side-mode suppression higher than 30 dB are obtained.
展示了一种近红外可调谐外腔激光器,该激光器使用电光偏转器和反射光栅作为可调谐滤波器。该偏转器是一种电子可重构的非像素化向列型液晶器件。通过控制施加到电光偏转器上的电压,可获得12纳米的调谐范围和高于30分贝的边模抑制。
