Physics laser frequency combs sheds light problem-solving skills
2019/10/23
Nature has a way of finding optimal solutions to complex problems. For example, despite billions of ways for a single protein to fold, proteins always fold in a way that minimizes potential energy. Sl...
Robust laser frequency stabilization by serrodyne modulation
Robust laser frequency stabilization serrodyne modulation
2012/2/28
We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic ...
Significant progress in Yb-fiber laser based frequency combs over the last few years resulted in sub-Hz relative comb-tooth linewidths, average powers over 60W and GHz comb spacings enabling novel app...
Digital Clock Recovery Algorithm for Optical Coherent Receivers Operating Independent of Laser Frequency Offset
Digital Clock Recovery Algorithm Optical Coherent Receivers Laser Frequency Offset
2015/7/30
We propose a digital clock recovery algorithm and demonstrate its tolerance to at least 5GHz laser frequency mismatch in a 43Gb/s DP-RZ-QPSK receiver after 1200km transmission.
Stabilization of diode-laser frequency to atomic transitions
laser stabilization dichroism
2011/4/26
Different methods of stabilization of diode lasers are reviewed with the emphasis on stabilization to atomic transitions. The stabilization methods to Doppler-broadened and Doppler-free resonances are...
