Explore the concept of negative feedback and its role in maintaining system stability across various applications.

Between the various models, spectral coverage is available from 355 to 1,550 nm with phase modulation of >2π radians. Diffraction loss is <5%. The SLMs have SVGA resolution of 800 × 600 pixels.

Methods are presented for determining the modulation limits of phase lock loop (PLL) FM demodulators. These limits establish the maximum deviation that the PLL can support (i.e., remain "inlock") ...

A new phase-matching factor is derived for four-wave mixing (FWM) that includes the effects of self-phase and cross-phase modulation in optical fibers. Theoretical results predict that the wavelength ...
