Latest Patents
Tianchi Sun holds a patent for a technology titled "Compact highly-stable synthesized RF sources using self mode-locked beat-notes of multi-modes lasers." This invention addresses the need for low phase noise signals generated in small structures. The technology utilizes a distributed Bragg reflector (DBR) based multi-mode laser combined with a mode-locking method to develop a frequency-stabilized and tunable RF signal generator. The output modes from each laser are adjusted using the reflecting bandwidth of the DBR and an electro-absorption modulator for amplitude control. The integrated laser system's phase section provides frequency tuning. Notably, mode-locking of 60 laser modes results in a highly frequency stable 10 GHz RF beat-note with a calculated phase noise of -150 dBc/Hz at a 10 kHz offset frequency.
