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…
Ultra-narrow linewidth hybrid integrated semiconductor laser
Youwen Fan, Albert van Rees, Peter J. M. van der Slot +6
We demonstrate a hybrid integrated and widely tunable diode laser with an intrinsic linewidth as narrow as 40 Hz, achieved with a single roundtrip through a low-loss feedback circu…
Automatic Delay Tuning of a Novel Ring Resonator-based Photonic Beamformer for a Transmit Phased Array Antenna
L. Bliek, S. Wahls, I. Visscher +5
We present a novel photonic beamformer for a fully integrated transmit phased array antenna, together with an automatic procedure for tuning the delays in this system. Such an auto…
A compact and reconfigurable silicon nitride time-bin entanglement circuit
C. Xiong, X. Zhang, A. Mahendra +13
Photonic chip based time-bin entanglement has attracted significant attention because of its potential for quantum communication and computation. Useful time-bin entanglement syste…
High precision wavelength estimation method for integrated optics
R. M. Oldenbeuving, H. Song, G. Schitter +5
A novel and simple approach to optical wavelength measurement is presented in this paper. The working principle is demonstrated using a tunable waveguide micro ring resonator and s…
25 kHz narrow spectral bandwidth of a wavelength tunable diode laser with a short waveguide-based external cavity
R. M. Oldenbeuving, E. J. Klein, H. L. Offerhaus +3
We report on the spectral properties of a diode laser with a tunable external cavity in integrated optics. Even though the external cavity is short compared to other small-bandwidt…
Modeling of mode-locking in a laser with spatially separate gain media
R. M. Oldenbeuving, C. J. Lee, P. D. van Voorst +2
We present a novel laser mode-locking scheme and discuss its unusual properties and feasibility using a theoretical model. A large set of single-frequency continuous-wave lasers os…
