A low noise, frequency stabilized, semiconductor based, 10.287 GHz mode-locked laser with 1000 finesse intracavity etalon is demonstrated with a timing jitter (1 Hz-100 MHz) of 10.9 fs and optical frequency fluctuations less than 150 kHz.
Using intracavity active phase modulation, we have verified the theory of Haus and Rana and realized timing jitter reduction from 304 fs to 150 fs integrated to Nyquist frequency on a 10.24 GHz actively mode-locked pulse train.
The comb dynamics of an etalon-based coupled optoelectronic oscillator are determined in terms of fixed-point frequencies. These measurements result in a stabilization scheme where changes to the optoelectronic phase and the laser cavity are decoupled.
We propose and experimentally demonstrate a novel intracavity modulation scheme to generate frequency shifted coherent pulses from a repetition rate multiplied harmonically mode- locked ring laser for range detection applications.
We report the generation of optical pulse trains with timing jitter of 770 attosecond (1 Hz -10 MHz) and 17.5 fs (extrapolated to Nyquist frequency) from a modelocked laser, using slab coupled optical waveguide amplifier.
Noise characteristics are studied for a self-stabilized laser utilizing the interplay between the intracavity dispersion and the optical frequency shift. The noise suppression bandwidth of this scheme is from 0 to ~100 KHz and showed the reduction of residual timing jitter (integrated from 0.9 Hz to 1 MHz) from 2.2fs to 660 attosecond which represents, to our knowledge, the lowest timing jitter reported...
Novel cavity engineering techniques are used to realize low noise, and stabilized optical frequency combs from quantum well and quantum dot based modelocked semiconductor diode lasers. Applications in high speed signal processing, secure communications and arbitrary waveform generation are highlighted
Two types of supermode noise, uncorrelated and correlated, are demonstrated for two different types of harmonically modelocked lasers. The correlated supermode noise is originated from the excitation of multiple correlated optical supermodes.
We report the generation of transform limited 4.0 ps optical pulse trains with ~100 mW of average output power from a modelocked laser, using a semiconductor slab coupled optical waveguide amplifier. A residual timing jitter of 8.5 fs (10 Hz -10 MHz) at 40 mW output power was also measured
