What is Cross-phase modulation?

In mathematical optimization, the criss-cross algorithm is any of a family of algorithms for linear programming. Variants of the criss-cross algorithm also solve more general problems with linear inequality constraints...

Phase-shift masks are photomasks that take advantage of the interference generated by phase differences to improve image resolution in photolithography. There exist alternating and attenuated phase shift masks. A phase-shift...

Cross tuning or cross-tuning is an alternative tuning used for the open strings of a string instrument. The term refers to the practice of retuning the strings; it also refers...

Phases of play are parts of a chess problem which happen, as it were, concurrently rather than consecutively. Each problem has at least one phase: the post-key play or actual...

The carrier-envelope phase or carrier-envelope offset phase is an important feature of an ultrashort laser pulse and gains significance with decreasing pulse duration, in a regime where the pulse consists...

Phase conjugation is a physical transformation of a wave field where the resulting field has a reversed propagation direction but keeps its amplitudes and phases.

Microfluidic modulation spectroscopy is an infrared spectroscopy technique that is used to characterize the secondary structure of proteins. Infrared spectroscopy is well known for this application.. However, the lack of...

In telecommunication, diurnal phase shift is the phase shift of electromagnetic signals associated with daily changes in the ionosphere. The major changes usually occur during the period of time when...

Phase-fired control , also called phase cutting or "phase angle control", is a method for power limiting, applied to AC voltages. It works by modulating a thyristor, SCR, triac, thyratron,...

A phase detector or phase comparator is a frequency mixer, analog multiplier or logic circuit that generates a signal which represents the difference in phase between two signal inputs. The...
