Summary: This work presents an optimized integrated multimode interferometer (MMI) based on a fully polymeric platform for the visible range. The device is manufactured using negative tone photoresists with small fabrication tolerance. Optical characterization reveals the best performance for a specific interferometric cavity dimension, and a process design kit is established for future use in complex photonic integrated circuit architectures.

Summary: Researchers have demonstrated slow light bimodal interferometric behavior in an integrated single-channel one-dimensional photonic crystal for the first time. This structure supports two electromagnetic modes with a large group velocity difference, resulting in over a 20-fold reduction in higher-order mode group velocity compared to other conventional interferometers. The proposed bimodal photonic crystal interferometer shows significant performance improvement in creating an ultra-compact optical modulator and a highly sensitive photonic sensor.

Summary: This article investigates the double-slit interferometer and the Mach-Zehnder interferometer with balanced beam splitters as prototypical setups for studying quantum wave-particle duality. It suggests that quantum coherence is more suitable than interferometric visibility for quantifying the wave aspect of a quantum system. The theoretical findings are experimentally verified using IBM quantum computers to simulate the optical Mach-Zehnder interferometer with biased beam splitters.

Summary: Optical sensing devices, particularly photonic crystal (PC) based sensors, have great potential in industrial and biomedical applications. In this study, a new type of Mach-Zehnder Interferometer (MZI) using low-symmetric Si PCs is proposed for efficient optical sensing of toxic gases and liquids. The interference phenomenon in the MZI allows for controlled location of dip and peak frequencies in the transmission spectra, enabling distinct observation of refractive index changes in surrounding media.

Summary: A post-distortion linearization technique for a semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) photonic sampler is proposed, and evaluated for both quasi-static and dynamic regimes. A significant improvement in total harmonic distortion (THD) is observed in the quasi-static regime, matching the highest THD improvement in the dynamic regime.

Summary: Efforts have been made to understand and control decoherence in 2D electron systems, with graphene offering a unique opportunity to study unexplored regimes of electron interferometry. A graphene quantum Hall PN junction exhibits a remarkable crossover from exponential decay to algebraic decay of interference visibility as temperature decreases, a previously unobserved phenomenon in GaAs interferometers.

Summary: The developed Ho:YAG chirped pulse amplifier, suitable for material processing applications, produces high-energy pulses with simple dispersion management, as both pulse stretching and compression are realized within a single chirped volume Bragg grating. Through studying laser ablation of a gold layer, it was found that short pulse durations are most suitable for achieving non-thermal ablation.

Summary: Optical coherence tomography (OCT) is a widely used imaging technique in the micrometer regime that has gained interest in medical imaging over the past twenty years. A quantitative model has been proposed in this study for a more realistic description of the OCT imaging process, taking into account system relevant parameters. The accuracy of the model has been illustrated through simulations and validated with experimental data from a 1300 nm swept-source OCT system after calibration of necessary system parameters.

Summary: Precise intraoperative brain tumor visualization is crucial for surgeons to achieve maximal safe resection. Recent studies have shown that protoporphyrin IX fluorescence-guided surgery can improve prognosis in patients with high-grade gliomas. This work demonstrates further optimization of the technique by minimizing the crosstalk of autofluorescence signal contributions, resulting in a clearer distinction between tumor fluorescence and autofluorescence background.
