The nature of the near-infrared interline sky background using fibre Bragg grating OH suppression

The case for OH suppression at near-infrared wavelengths

We calculate the advances in near-infrared astronomy made possible through the use of fibre Bragg gratings to selectively remove hydroxyl emission lines from the night sky spectrum. Fibre Bragg gratings should remove OH lines at high resolution (R = 10, 000), with high suppression (30dB) whilst maintaining high throughput (≈ 90 per cent) between the lines. Devices currently under construction s...

Infrared Radiation Detection Using Fiber Bragg Grating

Quantum theory of fibre Bragg grating solitons*

Following the pioneering work of Professor Haus, a general quantum theory for bi-directional nonlinear optical pulse propagation problems is developed and applied to study the quantum properties of fibre Bragg grating solitons. Fibre Bragg grating solitons are found to be automatically amplitude squeezed after passing through the grating and the squeezing ratio saturates after a certain grating...

Fibre Bragg Grating Filters for Optical Communications

Several steps in the development of Fibre optic Bragg grating for application in tuneable wavelength devices intended to DWDM are presented.

Antisymmetric pulse generation using phase-shifted fibre Bragg grating

Recent research in dispersion-managed systems for optical communications poses new challenges to the generation of soliton pulses. By deriving an approximate ordinary differential equation for the shape of the fundamental dispersion managed soliton, the existence of higherorder dispersion managed solitons was predicted [1]. The first antisymmetric solution was theoretically demonstrated to be r...
