Novel 3D Hollow Optical Waveguide with Lateral and Vertical Periodicity for Tunable Photonic Integrated Circuits
3D Hollow Optical Waveguide Lateral Vertical Periodicity Tunable Photonic Integrated Circuits
2015/7/17
A novel design-flexible 3D-hollow-waveguide with lateral- and vertical-periodicity has been demonstrated. A high-index-contrast-grating-(HCG), introduced as a lateral-periodicity, provides vertical as...
Tunable Photonic Microwave Notch Filter Based on a Dual- wavelength Fiber Laser
Tunable Birefringent Phase-Shift Induced Fiber Bragg Grating Shape Memory Alloy Ferrule
2015/7/15
We present a new method to induce low loss tunable birefringent phase shifts in fiber Bragg grating by applying mechanical stresses at precise locations along the FBG with a specially designed shape m...

Tunable Photonic Microwave Notch Filter Based Dual- wavelength Fiber Laser
2015/7/15
We experimentally demonstrate a tunable photonic microwave notch filter by employing two fiber Bragg grating-based dual wavelength laser. Based on the bending technique along the gratings, notch frequ...
Widely-tunable photonic-crystal-fiber optical parametric oscillator
High-resolution Refractive Index Sensing Solid-core Photonic Crystal Fibers
2015/8/4
We present a widely-tunable low-threshold all-fiber optical parametric oscillator. The tuning range of the output stretches from 23 to 164 THz above the pump frequency.
