Abstract

We demonstrate the frequency stabilization of a $1.5\mu \mathrm{m}$ laser diode (LD) with a low-intensity noise and a narrow linewidth to a ${}^{13}\mathrm{C}_2{\mathrm{H}}_2$ linear absorption line. The LD consists of an InP gain chip and an external Bragg reflector made of a PLC waveguide. By employing an external frequency modulator in a frequency stabilization circuit, an FM-eliminated optical output beam was obtained. The frequency stabilities reached as high as $2.3\times {10}^{-11}$ for $\tau =1\mathrm{s}$ and $9.1\times {10}^{-12}$ for $\tau =100\mathrm{s}$. Furthermore, an RIN of less than $-135\mathrm{dB}∕\mathrm{Hz}$ and a linewidth of $4\mathrm{kHz}$ were simultaneously achieved.
