Welcome to San Francisco, California and the 25th IEEE Photonics Conference (previously known as the IEEE LEOS Annual Meeting). Following in the path of previous successful meetings, this year's conference features an extensive range of technical activities in addition to some unique events.
We describe a dual-frequency dual-polarization class-A vertical external-cavity semiconductor laser delivering a tunable optically-carried microwave signal with an additive phase noise below −120 dBc/Hz at 10 kHz.
The transient response of a directly modulated injection-locked semiconductor laser operated in the period-one state is analyzed theoretically and verified experimentally. The results illustrate the limits and stability properties of the modulated microwave subcarrier frequency.
A passive polarization mode convertor monolithically integrated within the cavity of a semiconductor laser is reported. A TE-to-TM conversion efficiency of more than 90% is obtained using compound back-to-back sub-wavelength air trenches
The adiabatic chirp for antireflection/high-reflection DFB laser is mostly dependent on high-reflection facet phase independently of the antireflection quality while very low reflectivity allows chirp predicting from the laser emission spectrum.
The generation of ultrashort optical pulses by semiconductor lasers has been extensively studied for many years. A number of methods, including gain-/Q-switching and different types of mode locking, have been exploited for the generation of picosecond and sub-picosecond pulses [1]. However, the shortest pulses produced by diode lasers are still much longer and weaker than those that are generated...
Pulses emitted by an excitable (asymmetric) semiconductor ring laser are experimentally and theoretically characterized. We numerically show that it is possible to mimic neural functionality by considering them in a coupled configuration.
All-fiber-based narrow linewidth nanosecond pulsed lasers in MOPA configuration are reviewed, and their applications in nonlinear frequency conversion are discussed.
Modeling results for lateral-longitudinal mode discrimination in longitudinally inhomogeneous finite-length waveguides of ridge lasers are presented, obtained by numerical solutions of the wave equation and calculations of the mode thresholds, predicting high-brightness single-mode output of wide stripes.
Adiabatically flared slab-coupled optical waveguide lasers (SCOWLs) at 1.06 µm wavelength have been studied, achieving a large fundamental mode and a 32% increase in COD power. Capabilities and limitations of the taper mechanism are discussed.
Optical gain properties of InGaN quantum wells on ternary substrates are analyzed for visible lasers. Larger optical gains are obtained by employing ternary substrates, which indicate its potential for green-emitting diode lasers.
We present a 7nm bare InGaAsP quantum well coupled to a gold nanorod. Photoluminescence measurements show an increased spontaneous emission rate of at least 4.5× without sacrificing efficiency.
III–V semiconductor photonic crystal nanolasers are heterogeneously integrated on a SOI waveguides circuitry. We demonstrate this approach constitutes an efficient way to interface these ultimate lasers. Coupling efficiency and optical bistability will be discussed.
We demonstrate a novel saturable absorber based on diamond thin film directly synthesized on quartz substrates by microwave plasma chemical vapor deposition method. The function of mode-locking for the fiber laser is achieved utilizing the diamond thin film.
We demonstrate a Sampled Grating-Distributed Bragg Reflector (SG-DBR) laser offset locked at 6.5 GHz from a diode mode-locked laser comb using an integrated optical phase-locked loop (OPLL).
A new photonics integrated circuit for the demultiplexing and amplification of coherent combs is designed and demonstrated. The circuit utilises injection locking as a technique to amplifiy and maintain coherence between optical lines. Coherence between the optical lines of the device is analysed.
Optical dipole nano-antennas are passive devices needing light from external sources. In this work, highly efficient coupling of light from microdisk lasers into plasmonic nano-antennas by using nano-tapers is proposed.
