Chromatic dispersion vs wavelength. Inset: SEM image of the solid-core PCF.
Experimental setup. MO denotes microscope objective (×20), OSA denotes optical spectrum analyzer (0.1 nm resolution), and HWP denotes half-wave plate.
(a) Gain spectrum of the PCF-based parametric amplifier at . Circles denote experimental results. Solid curve denote standard analytical gain theory. (b) Input and output spectra for a signal wavelength located at 1078 nm.
Experimentally measured parametric gain vs the peak pump power for a signal wavelength at 1081 nm. Signal input . The solid line is a linear theoretical fit. Inset: saturated FOPA spectrum indicated by the arrow.
