ABSTRACT:
Optical pulse compression is of importance in very high bit rate optical fiber communication systems. We are disclosing an adiabatic optical pulse compressor that can achieve substantial compression by means of a relatively short (e.g., about 100 cm) chirped periodic structure, exemplarily an apodized and chirped fiber Bragg grating. The input pulse to the periodic structure typically are not soliton pulses, but the passage through the periodic structure results in transformation of the pulses into substantially transform-limited soliton pulses that are available (typically after appropriate modification) for transmission through conventional optical fiber towards utilization means. The input pulses can be generated by any applicable method, e.g., by combining the cw outputs of two lasers that differ with regard to the frequency of their output.
