Abstract :
We have designed a monolithic optical frequency comb generator (M-OFC-G) that uses an external coupled cavity for the 1.5-μm region. The comb envelope was observed with a span or 6.3 THz and the total cavity transmission has been 16%. With an additional etalon inside the external coupled cavity, the comb envelope spanned 7 THz while the transmission dropped to 9%. We also demonstrated the possibility of increasing the power of selected sidebands by using a coupled cavity at the output port of the M-OFC-G. We observed an increase of the power of the selected sidebands within a range of 5.6 THz.
