Summary: A new class of optical parametric oscillators based on a 20-micrometer-long semiconductor photonic crystal cavity is reported, operating at telecom wavelengths. These oscillators are able to achieve parametric oscillation by thermally tuning high-quality-factor modes into a triply resonant configuration, with a estimated pump power threshold of 50-70 microwatts. This source behaves as an ideal degenerate optical parametric oscillator, paving the way towards efficient nonlinear sources of squeezed light or entangled photons pairs in quantum optical circuits.

Summary: By utilizing two-dimensional photonic crystals and a one-dimensional PhC nano-beam cavity, researchers developed all-polymeric dye-lasers on a suspended poly-methylmethacrylate film and evaluated their potential as attachable strain sensors. They experimentally confirmed the stable lasing performances of the dye-laser on a rough surface, and theoretically studied the wavelength responses of the PhC resonators to stretching strain, further improving them through strain shaping concept. The thin film PhC dye-lasers demonstrated high attachability and strain sensing response, showing promise as attachable strain sensors.

Summary: We propose an improved method for accurately transferring a photonic crystal nanobeam laser onto a SiN(x) waveguide. Our method achieves smaller transfer printing misalignments compared to the conventional visual alignment approach. Experimental results show the high accuracy and reproducibility of our method, with mean rotational misalignment of 0.08° and mean displacement misalignment of 26 nm for 48 docked NB lasers at the SiN(x) waveguides. Over 97% of these accurately docked lasers demonstrated uniform unidirectional coupling to specific waveguide output facets. Our study provides a highly promising method for integrating nanowire-based light sources into silicon-based photonic integrated circuits.

Summary: In this study, we demonstrate that cascading multiple bichromatic photonic crystals can significantly increase the quality factor without increasing the overall device size. Using a lithium niobate photonic crystal as an example, we show that the simulated quality factor of the cascaded cavity can reach 10^5 with a 70 degrees slant angle, which is an order of magnitude larger than that in an isolated cavity. The proposed device can be easily fabricated using current etching techniques for lithium niobate. This work provides guidance for the design of photonic crystal cavities with high quality factors.

Summary: The radiation properties of pointlike sources like molecules or semiconductor quantum dots can be modified by changing the surrounding photonic environment, which is a core concept in cavity quantum electrodynamics (CQED). Quantum dots in photonic crystal microcavities have been used as a model system to study these effects and for creating efficient single-photon quantum emitters. Recent research has shown that quantum interference of exciton recombination paths through cavity and free-space modes can change the radiation significantly. This study reports experimental evidence of this effect in the emission spectra of quantum dots placed in specific locations within a photonic crystal cavity, showing asymmetry in the polarization-resolved emission spectra depending on the quantum dot position.

Summary: An optomechanical scheme is presented to achieve light-controlled logic functions by combining an electromagnetic resonator with a strongly nonlinear nanomechanical oscillator. The nonlinear mechanical oscillations, controlled by external drives, are sensitive to incident light due to enhanced light-matter interactions. Reconfigurable logic functions (NOT, XOR, OR, AND) can be realized by adjusting the initial mechanical configurations to obtain various responses to input optical signals.

Summary: The emission dynamics of a multimode broadband interband semiconductor laser have been examined through experimentation and theory. The study reveals the presence of a modulational instability in the nonlinear dynamics of a III-V semiconductor quantum well surface-emitting laser, observed in the anomalous dispersion regime. An additional unstable region arises in the normal dispersion regime due to carrier dynamics, which is not found in systems with fast gain recovery. The interplay between cavity dispersion and phase sensitive non-linearities is shown to significantly impact the laser emission behavior.

Summary: The article discusses the properties of a recently introduced photonic crystal parametric oscillator, which achieves Canonical Resonant Four-Wave-Mixing by allowing only four (three in the degenerate case) modes of the cavity to interact through this parametric process. The study includes a statistical analysis of over 100 resonators and 10 parametric oscillators, assessing their robustness against fabrication tolerances and evaluating their performance in terms of average values and dispersion. The article also highlights the minimum pump power at threshold and the relationship between the cavity photon lifetime and three photon absorption as conditions for parametric oscillation.
