An effective method for millimeter-wave (mmW) carrier generation from a dual-transverse-mode microsquare laser is experimentally demonstrated. By directly modulating the dual-mode microsquare laser at 6.7 GHz, multiple sidebands are generated due to enhanced modulation nonlinearity, and the lasing modes with an interval of 40 GHz are phase-locked. MmW carriers up to 47 GHz, corresponding to seven times that of the modulation frequency, are achieved with a linewidth below 10 Hz. The single-sideband phase noises of the signals keep the same level after transmission over 2.5 km of optical fiber.

利用调制边带通过双模微平方激光锁相产生低相位噪声微波

实验证明了一种有效的方法，可以从双横模微平方激光器产生毫米波（mmW）载流子。通过直接调制6.7 GHz的双模微平方激光器，由于增强的调制非线性而产生多个边带，并且间隔40 GHz的激光模式被锁相。线宽低于10 Hz，可获得高达47 GHz的MmW载波，相当于调制频率的7倍。信号的单边带相位噪声在2.5 km的光纤上传输后保持相同的水平。
