Abstract:
1. An apparatus for altering a chirp of an input light comprising: a first grating structure positioned to receive the input light to produce a first dispersed light; a first electro-optical block positioned relative to the first grating structure to receive the first dispersed light which exits the first electro-optical block as a second dispersed light; a second grating structure positioned relative to the first electro-optical block to receive the second dispersed light to produce a first collinear light; a third grating structure positioned relative to the second grating structure to receive the first collinear light to produce a third dispersed light; a second electro-optical block positioned relative to the third grating structure to receive the third dispersed light which exits the second electro-optical block as a fourth dispersed light; a fourth grating structure positioned relative to the second electro-optical block to receive the fourth dispersed light to produce an output light; and wherein a voltage applied to the first and second electro-optical blocks alters the chirp of the output light.
