Abstract
An apparatus for altering a chirp of an input light comprising one or more grating structures and one or more electro-optical blocks. In which a voltage is applied to the one or more electro-optical blocks to alter a chirp of light exiting the apparatus.
Claims18
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.

An apparatus for altering a chirp of an input light comprising:
- a grating structure;
- and
- an electro-optical block;
- wherein the input light is spatially dispersed by the grating structure a series of four times;
- wherein after the input light is dispersed by the grating structure the first time it passes through the electro-optical block a first time;
- wherein after the input light is dispersed by the grating structure the third time it passes through the electro-optical block a second time;
- wherein after the input light is dispersed a fourth time by the grating structure it is output as chirped output light;
- and
- wherein a voltage applied to the electro-optical block alters the chirp of the output light.
