Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing
Laser &Photonics Reviews, EarlyView.Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Infiltrated Photonic Crystal Fibers for Sensing Applications
Sensors, 2018 Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic arrangement of microstructured holes located in the fiber’s cladding. Light confinement is achieved by means of either index-guiding, or the photonic bandgap effect in a

Optofluidic microchannels in aerogel [PDF]
Optics Letters, 2011 We report optofluidic waveguides made by filling microchannels in aerogel with water. The aerogel cladding is a nanoporous material with an extremely low refractive index of ~1.05, giving a large index step from the water core. Channels were formed by removing embedded optical fibers, which could be nonuniform or multiple.

Optofluidic Grating Spectrograph on a Chip [PDF]
Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009 We demonstrated liquid metal based optical components such as mirrors and reflection gratings for building on-chip optofluidic spectrographs and monochromators. We designed a Czerny-Turner spectrograph with 1.7nm resolution, 200nm FSR and a footprint of 3cm by 3cm.
