Ring resonator enhanced mode-hop-free wavelength tuning of an integrated extended-cavity laser
Albert van Rees, Youwen Fan, Dimitri Geskus +4
Extending the cavity length of diode lasers with feedback from Bragg structures and ring resonators is highly effective for obtaining ultra-narrow laser linewidths. However, cavity…
Hybrid integrated semiconductor lasers with silicon nitride feedback circuits
Klaus-J. Boller, Albert van Rees, Youwen Fan +17
Hybrid integrated semiconductor laser sources offering extremely narrow spectral linewidth as well as compatibility for embedding into integrated photonic circuits are of high impo…
An X-Ray Regenerative Amplifier Free-Electron Laser Using Diamond Pinhole MIrrors
Henry P. Freund, Peter van der Slot, Yuri Shvyd'ko
Free-electron lasers (FELs) have been built ranging in wavelength from long-wavelength oscillators using partial wave guiding through ultraviolet through hard x-ray FELs that are e…
Integrated frequency comb laser with narrow intrinsic optical linewidth based on a dielectric waveguide feedback circuit
Jesse Mak, Albert van Rees, Youwen Fan +4
We present an integrated hybrid semiconductor-dielectric (InP-SiN) waveguide laser that generates frequency combs at a wavelength around 1.5 m with a record-low intrinsi…
