Phase Shift of Reverse Biased p-n Junction Arrays by Fourier Methods

Electric Field Distribution in a Reverse-Biased p-n Junction

This problem is motivated by the use of crystals as detectors of energetic charged particles that pass completely through the crystal, leaving a trail of electron-ion pairs. Although the crystals are nominally insulators, the electrons so liberated are in the conduction band and can be separated from the ion by a DC electric field, resulting in a signal pulse on the electrodes plated onto oppos...

Phase regeneration of DPSK signals in a silicon waveguide with reverse-biased p-i-n junction.

Phase regeneration of differential phase-shift keying (DPSK) signals is demonstrated using a silicon waveguide as nonlinear medium for the first time. A p-i-n junction across the waveguide enables decreasing the nonlinear losses introduced by free-carrier absorption (FCA), thus allowing phase-sensitive extinction ratios as high as 20 dB to be reached under continuous-wave (CW) pumping operation...

Fourier-transform method of phase-shift determination.

A new phase-shifting interferometry analysis technique has been developed to overcome the errors introduced by nonlinear, irregular, or unknown phase-step increments. In the presence of a spatial carrier frequency, by observation of the phase of the first-order maximum in the Fourier domain, the global phase-step positions can be measured, phase-shifting elements can be calibrated, and the accu...
