Abstract

A sol-gel-based external cavity DBR laser with narrow linewidth is described. The sol-gel waveguide grating is formed on the SiO₂-coated silicon substrate with a loss of about 0.2 dB/cm. The threshold current is 32 mA at the lasing wavelength of about 1530 nm and T = 20°C. The side-mode suppression is close to 30 dB at 43 mA. The laser linewidth is less than 500 kHz.
