Multi-Watt Supercontinuum Generation from 0.3 to 2.4 μm in PCF Tapers
2007 Edition, May 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Supercontinua spanning 320-2400nm have been generated in long photonic-crystal-fiber tapers. Total average powers of over 3.5W and spectral-power-densities in the blue of over 5mW/nm are demonstrated. Use as a broadly-tunable pulse source is proposed.

Hole-size increasing PCFs for blue-extended supercontinuum generation
2013 Edition, May 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Supercontinuum (SC) sources with spectra extending into the deep-blue region below 400 nm are highly desirable in areas such as fluorescent microscopy [1]. Tapering of photonic crystal fibers (PCFs) with high air-fill fractions has proven an effective way of extending...

On-fiber 3D printing of photonic crystal fiber tapers for mode field diameter conversion
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. The large mismatch between the Mode Field Diameter (MFD) of conventional single-mode fibers (SMFs) and the MFD of highly nonlinear Photonic Crystal Fibers (PCFs), that can be down to 1.5 μm, or Large Mode Area PCF, that can be up to 25...

Broadly-tunable near- and mid-IR source by direct pumping of an OPA with a 42 MHz femtosecond multi-Watt Yb:KGW oscillator
2013 Edition, May 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Laser sources delivering high repetition rate broadband mid-IR radiation enable a number of key applications [1], for example in near-field and FTIR spectroscopy [2]. Here, we present an OPA that is directly pumped by a diode-pumped solid-state oscillator without the need for any...

Towards multi-mJ, OPCPA-based field synthesizer
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Combining the concept of temporal field synthesis with optical parametric chirped pulse amplification (OPCPA) holds promise for generation of multi-mJ, watt-level light transients, which may extends isolated attosecond pulse to multi-keV photon energies [1,...

Multi-octave mid-infrared supercontinuum generation in dispersion-engineered AlGaAs-based strip waveguides
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose and numerically investigate mid-infrared supercontinuum generation in dispersion-engineered Al0.18Ga0.82As-based strip waveguides. An ultra-board supercontinuum ranging from 2 to 15.9 μm is obtained when pump pulses with center...

Magnetic Field Sensor Based on Photonic Crystal Fiber Taper Coated With Ferrofluid
2015 Edition, Volume 27, January 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel and compact magnetic field sensor based on a tapered photonic crystal fiber (PCF) coated with ferrofluid is proposed. It consists of a section of tapered PCF, which is spliced between two single-mode fibers with a waist diameter of 24 μm. The ferrofluid is...

Low Dispersion Photonic Crystal Fiber for OAM Mode
2018 Edition, October 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we design a new type of photonic crystal fiber (PCF), which can transmit 26 orbital angular momentum modes (OAMs), by inserting a kind of micro-structure to common total internal reflection PCF. Compared with the original PCF for reference, the...

Monolithic Integration of $\rm Al_{2}O_{3}$ and $\rm Si_{3}N_{4}$ towards Double-layer Active-passive Platform
