Summary: Bragg gratings (BGs) are widely used in microwave photonic signal processing and systems due to their customizable amplitude and phase responses. Waveguide BGs (WBGs) are compact and easily integrated with other components to build MWP systems. Subwavelength grating (SWG) waveguides and passive devices in silicon-on-insulator (SOI) have enabled the development of breakthrough devices based on anisotropic metamaterials.

Summary: This study demonstrates the use of a MISIM waveguide structure for ethanol sensing, showing that in the presence of harmful ethanol, the electric field in a low refractive index slot undergoes a red-shift in wavelength. By adjusting the silicon porosity and physical dimensions, the red-shift can be controlled. The optimized sensor metrics obtained through simulations and the fabrication stages are described. The sensor is found to be feasible for ethanol detection in hazardous environments.

Summary: This paper introduces four basic bending methods and proposes an n-adjustable (NA) bend that can achieve lower losses compared to other basic bends by adjusting n values. The circular bend and Euler bend are special cases of the proposed NA bend. The proposed bend shows promise as a candidate for low-loss compact photonic integrated circuits.

Summary: Theoretical study on pulse evolution dynamics in two-stage temporal compression using a graphene-silicon hybrid waveguide as a phase modulator showed that by utilizing saturable absorption (SA) and repressing linearly intensity-dependent absorption (IDA), pedestal-free temporal shape and minimized temporal acceleration can be achieved. Meanwhile, enhancing linearly intensity-dependent refraction (or Kerr effect) contributes to reducing device size and input power of pulse, benefiting the development of graphene-based all-optical modulators in photonic integrated circuits.

Summary: A novel composite waveguide based on hybrid substrate integrated waveguide and spoof surface plasmon polariton (SIW-SSPP) is proposed in this paper. By utilizing different feeding methods, the odd mode and even mode of SSPP are excited simultaneously and operate at the same frequency band, achieving co-frequency mode multiplexing for the proposed odd-even mode composite waveguide (OEMCW). Experimental results demonstrate that the proposed waveguide can operate in the range of 10.3 GHz to 18 GHz with significant isolation between the modes.

Summary: A novel and integrated plasmonic full adder based on cascaded rectangular ring resonators for optical computing is proposed. The plasmonic resonators covered by graphene layer can work as all-optical switches with low power consumption and ultrashort response time. Finite-difference time-domain (FDTD) simulation results verify the successful realization of full-adder operations. This plasmonic device offers a new concept for designing optical computing devices with small feature size, fast response time, and lower power consumption.

Summary: This study explores a two-step process for synthesizing silicon clathrate film on a diamond silicon wafer and identifies key factors impacting film quality. Two approaches are systematically developed to minimize the effects of defective structures, resulting in high-quality clathrate surfaces and films for more reliable optical measurements. Techniques presented in this work pave the way for Si clathrate thin film to be an optically efficient alternative crystalline form of Si in optoelectronic applications.
