Fluidic optics is a new class of optical system with real-time tunability and reconfigurability enabled by the introduction of fluidic components into the optical path. We describe the design, fabrication, operation of a number of fluidic optical systems, and focus on three devices – liquidcore/liquid-cladding (L) waveguides, microfluidic dye lasers, and diffraction gratings based on flowing, c...

We experimentally demonstrate, for the first time, polarization-insensitive wavelength conversion of a 10 Gb/s NRZ-OOK data signal based on four-wave mixing in a silicon nanowire with bit-error rate measurements.

We report the first supercontinuum generated in a gas-filled single-ring hollow-core PCF. When pumped with ultrashort pulses at 1500 nm, the emitted spectrum spans three octaves from the deep ultraviolet to the mid-infrared. OCIS codes: (060.0060) Fiber optics and optical communications; (190.0190) Nonlinear optics (320.0320) Ultrafast optics

Non-local means image denoising method is optimized to boost the performance of Brillouin distributed fiber sensors. Results demonstrate ultra-long sensing over a 200-km fiber-loop with 2m resolution using a sensing scheme without any hardware sophistication. OCIS codes: (060.2310) Fiber optics; (060.2370) Fiber optics sensors; (290.5900) Scattering, stimulated Brillouin; (060.4370) Nonlinear o...

Nonlinear Optics has continued to develop over the last few years at an extremely fast pace, with significant advances being reported in nonlinear optical metamaterials, optical signal processing, quantum optics, nonlinear optics at subwavelength scale, and biophotonics. These exciting new developments have generated significant potential for a broad spectrum of technological applications in wh...

Massive fiber-to-the-home network deployment requires never ending equipment upgrades operating at higher bandwidth. We show effective signal slicing method, which can reuse low bandwidth opto-electronical components for optical communications at higher bit rates. OCIS codes: (060.2330) Fiber optics communications; (060.2360) Fiber optics links and subsystems; (060.0060) Fiber optics and optica...

A new type of adaptive optics system is proposed for astronomical imaging. It replaces the wavefront sensing and modulation hardware pieces of conventional adaptive optics with numerical processing capabilities of digital holography of incoherent sources. OCIS codes: (010.1080) Active or adaptive optics; (090.1000) Aberration compensation; (090.1995) Digital holography; (110.0115) Imaging throu...
