Lithographically defined cavities with high Quality and Purcell factors
JPhys PhotonicsWe introduce and analyze a lithographically defined cavity (Li-cavity) incorporating a buried mesa defect in a planar vertical structure, which induces transverse photonic confinement while enabling compatibility with electrical injection.

Single-Mode-Multimode-Single-Mode Fiber (SMS): Exploring Environmental Sensing Capabilities
IEEE Sensors LettersIn this paper, we study the environmental sensing capabilities of a Single-Mode-Multimode-Single-Mode (SMS) fiber in a simple low-cost configuration. SMS fibers exhibit sensitivity to temperature, humidity, refractive index and strain, making them suitable for numerous applications in telecommunications, environmental monitoring, and more.

Double-Clad Anti-Resonant Hollow-Core Fiber With Inner Cladding Tube Offset for Mode Tailoring
IEEE Photonics JournalWe demonstrate a double-clad anti-resonant hollow-core fiber (DC-ARF) with an offset inner cladding structure for effective mode tailoring. The DC-ARF consists of six thin-walled, azimuthally offset inner tubes enclosed within a thicker outer cladding ...

High Sensitivity Refractometer Based on a Tapered-Single Mode-No Core-Single Mode Fiber Structure
Sensors, 2019 We have proposed a novel tapered-single mode-no core-single mode (TSNS) fiber refractometer based on multimode interference. The TSNS structure exhibits a high contrast ratio (>15 dB) and a uniform interference fringe.
