Abstract

The spectral sensitivity of photodiode-based optoelectronic chromatic dispersion is enhanced by phase-shift amplification using RF interferometry. With phase-shift amplification of G = 4 · 104, a peak phase-shift sensitivity of ∆θ = 27 deg/pm is achieved, corresponding to a spectral resolution of ∆λres = 1 fm. This all-electronic solid-state technology can serve as an on-chip inexpensive technique for femtometer-resolved wavelength monitoring.
