| Research Abstract |
This research was executed about the following :
(a) Investigation for optical wave control of supercontinuum (SC) near a 1.55-μm wavelength range:
Optical wave control of Supercontinuum (SC) spectrum near a 1.55-μm wavelength range:
Supercontinuum (SC) spectrum phases of 1.55-μm near a wavelength range was investigated by numerical analysis.
(b) Investigation for optical wave control of supercontinuum (SC) near a 1-μm wavelength range:
Recently, optical pulses propagating through a tapered fiber (TF) immersed in heavy water (D2O) or photonic crystal fi ber (PCF) of a special design were reported to yield a broad and fl at supercontinuum (SC) spectrum because the fi ber dispersion characteristics are of low dispersion around 1000 nm. This study was undertaken to investigate spectral intensities and phase distributions of SC pulses generated in low-dispersion fi bers. Results show that highly nonlinear PCF with group velocity dispersion (GVD) distributions having an extremum value and zero dispersion around 1000 nm is useful at short fiber length for applications in which the phase distribution is a concern.
Moreover, the spatial light modulator space phase modulator (SLM) was selected and purchased, and the device for assembling a optical wave control system was fabricated.
