1. A distributed Bragg reflector (DBR] based multi-mode laser having mode-locking capability to build a frequency stabilized and tunable RF signal generator comprises: a distributed Bragg reflector (DBR] used as a filter to select laser output frequency; a gain medium;
a phase tuning section; and
an electro-absorption amplitude modulator;
wherein more than one multi-mode lasers share the DBR reflector;
wherein the gain medium is designed using InGaAsP—InAsP multi quantum well structure for operation at about 1550 nm, where a threshold current of about 30 mA is estimated for multi-mode lasers using 7 wells of 5-7 nm wide and gain section length of 500 um to 1500 um.
