Physics of Widely Tunable VCSELs with Coupled Cavities

The behavior of a tunable VCSEL is governed by the resonances of a semiconductor cavity and an air cavity. By designing a semiconductor cavity which is antiresonant at the tuning center, the free spectral range is maximized at the edges of the tuning range.
