Monolithically Integrated Wavelength-Routing Switch Using Tunable Wavelength Converters with Double-Ring-Resonator Tunable Lasers
We present an 8 × 8 wavelength-routing switch (WRS) that monolithically integrates tunable wavelength converters (TWCs) and an 8 × 8 arrayed-waveguide grating. The TWC consists of a double-ringresonator tunable laser (DRR TL) allowing rapid and stable switching and a semiconductor-optical-amplifier-based optical gate. Two different types of dry-etched mirrors form the laser cavity of the DRR TL...
متن کاملSemiconductor nanowire ring resonator laser.
Nanowires of the wide band-gap semiconductor gallium nitride (GaN) have been shown to act as room-temperature uv lasers. Recent advances in nanomanipulation have made it possible to modify the shape of these structures from a linear to a pseudoring conformation. Changes to the optical boundary conditions of the lasing cavity affect the structure's photoluminescence, photon confinement, and lasi...
متن کاملWidely tunable diode lasers advance microresonator research
Due to a very distinct spectrum of resonant frequencies, the characterization of optical microcavities calls for widely tunable sources of continuous wave laser light, offering suitably narrow linewidths and single-mode operation over the entire tuning range. This is why external cavity diode lasers, which allow for mode-hop free wavelength tuning, often over more than a hundred nanometers, hav...
متن کاملHigh-power widely tunable thulium fiber lasers.
Applications requiring long-range atmospheric propagation are driving the development of high-power thulium fiber lasers. We report on the performance of two different laser configurations for high-power tunable thulium fiber lasers: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the oscillat...
متن کاملInP-Based Passive Ring-Resonator-Coupled Lasers
Design of passive ring-coupled lasers based on InGaAsP waveguides is investigated using beam propagation method. Mode coupling, propagation loss due to bending, and scattering loss from waveguide sidewall roughness are taken into account. By compromising threshold gain, linewidth and side-mode suppression ratio (SMSR), suitable waveguide width and coupling strength are determined for different ...
