Compact Silicon Slot Waveguide Intersection Based on Mode Transformation and Multimode Interference [PDF]
IEEE Photonics Journal, 2017 Silicon slot waveguide intersections are necessary for photonic-integrated circuits based on silicon slot waveguides. We theoretically investigate a compact silicon slot waveguide intersection, which consists of mode transformers and a multimode strip ...

Combining Four Gaussian Lasers Using Silicon Nitride MMI Slot Waveguide Structure. [PDF]
Micromachines (Basel), 2022 Transceivers that function under a high-speed rate (over 200 Gb/s) need to have more optical power ability to overcome the power losses which is a reason for using a larger RF line connected to a Mach–Zehnder modulator for obtaining high data bitrate ...

Slot-Waveguide Silicon Nitride Organic Hybrid Distributed Feedback Laser. [PDF]
Sci Rep, 2019 One of the major barriers for a widespread commercial uptake of silicon nitride photonic integrated circuits for cost-sensitive applications is the lack of low-cost monolithically integrated laser light sources directly emitting into single-mode ...

Optical Slot-Waveguide Based Biochemical Sensors [PDF]
Sensors, 2009 Slot-waveguides allow light to be guided and strongly confined inside a nanometer-scale region of low refractive index. Thus stronger light-analyte interaction can be obtained as compared to that achievable by a conventional waveguide, in which the ...
