“…Nonlinear optics provides a good way to generate new optical frequencies spaced a predictable and controllable distance from a strong pump frequency and is thus well-placed to take advantage of commercially available sources at shorter wavelengths to generate mid-IR spatial and/or temporally coherent radiation. Supercontinuum generation (SCG) has received a lot of attention from researchers in recent years [1] because of the breadth of its potential applications such as in optical coherence tomography [2], wavelength division multiplexing in telecommunications [3,4], in optical sensing [5] and in spectroscopy [6,7]. A lot of the work in supercontinuum generation has focused on the use of photonics crystal fibers [2].…”

A 1000 nm wide supercontinuum, spanning from 1470 nm in the telecom band to 2470 nm in the mid-infrared is demonstrated in a 800 nm x 220 nm 1 cm long hydrogenated amorphous silicon strip waveguide. The pump source was a picosecond Thulium doped fiber laser centered at 1950 nm. The real part of the nonlinear parameter of this waveguide at 1950 nm is measured to be 100±10 W -1 m -1 , while the imaginary part of the nonlinear parameter is measured to be 1.2±0.2 W -1 m -1 . The supercontinuum is stable over a period of several hours, as the hydrogenated amorphous silicon waveguides do not degrade when exposed to the high power picosecond pulse train.

“…To achieve this, a possible method is to use a single supercontinuum (SC) as the multiwavelength optical source. To construct large flexible optical networks, and utilize both OTDM and WDM technologies, SC broad-band optical source has received much attention in recent years [19]- [24].…”

Abstract-A performance analysis of an optical clock extraction circuit based on a Fabry-Perot filter (FPF) is presented. Two analytical methods, time-domain and frequency-domain analysis, are developed in this paper. Time-domain analysis shows that there is no phase jitter in the extracted optical clock if the free spectral range (FSR) of the FPF is exactly equal to the signal clock frequency. Based on this, we obtain an analytical expression for root mean square (rms) amplitude jitter of the extracted optical clock in time domain, in which we have taken the impacts of carrier frequency drift and carrier phase noise into account. When the FSR of the FPF deviates from the signal clock frequency, both phase jitter and amplitude jitter will occur in the extracted optical clock. In this situation, a more general frequency-domain method is developed to deal with the timing performance under the assumption that carrier phase noise is negligible. This method allows us to calculate both rms phase jitter and rms amplitude jitter of the extracted optical clock. Using the developed two methods, we present a detailed numerical investigation on the impacts of finesse of the FPF, carrier frequency drift, resonator detuning, carrier phase noise, and optical pulse chirp on the timing performance. Finally, the application of this circuit in multiwavelength clock recovery is discussed.

“…Supercontinuum lasers generated using optical fibers provide nearly single mode output with very high brightness, and finds applications in a variety of fields like spectroscopy, OCT, LIDAR and communications [2][3][4]. In principle, supercontinuum can be generated in any nonlinear medium by pumping very high intensity of light into it.…”

Abstract:We demonstrate a simple module for octave spanning continuous-wave supercontinuum generation using standard telecom fiber. This module can accept any high power Ytterbium-doped fiber laser as input. The input light is transferred into the anomalous dispersion region of the telecom fiber through a cascade of Raman shifts. A recently proposed Raman laser architecture with distributed feedback efficiently performs these Raman conversions. A spectrum spanning over 1000nm(>1 octave) from 880-1900nm is demonstrated. The average power from the supercontinuum is ~34W with a high conversion efficiency of 44%. Input wavelength agility is demonstrated with similar supercontinua over a wide input wavelength range.
