Pulse compression using a tapered microstructure optical fiber

Pulse compression using a tapered microstructure optical fiber.

We calculate the pulse compression in a tapered microstructure optical fiber with four layers of holes. We show that the primary limitation on pulse compression is the loss due to mode leakage. As a fiber's diameter decreases due to the tapering, so does the air-hole diameter, and at a sufficiently small diameter the guided mode loss becomes unacceptably high. For the four-layer geometry we con...

2. High Repetition Rate Pulse Source Using Pulse Compression through Optical Fiber

For next-generation optical networks, it is expected that transmission capacity will be increased by making high channel density and wide band WDM systems, and increasing data bitrate per wavelength channel. The high bitrate per channel system has great potential for cost reductions in comparison with wide broaden DWDM systems of the same transmission capacity, because of a fewer number of chan...

Pulse Propagation in Optical Fiber Using Wavelets

The propagation of optical pulses in a single mode fiber is analyzed by solving nonlinear Schrödinger (NLS) equation numerically. The propagation is modeled using a split-step wavelet method, analogous to the split-step Fourier method, while retaining the advantages of the wavelet transform. Pulses and pulse sequences are accommodated with equal ease, as is frequency chirping of the light sourc...

Highly nondegenerate femtosecond four-wave mixing in tapered microstructure fiber

Theory of parabolic pulse generation in tapered fiber.

We examine similarities and differences between high-power parabolic pulse generation in an active medium and in tapered fiber with decreasing normal dispersion. Using a realistic tapered fiber design, we demonstrate the possibility of parabolic pulse generation without an external pump and determine the limitations of this approach.
