Classification: CPC H | IPC H

Claim 9:
10. A pulse transformer for modifying the amplitude and phase of short optical pulses, the pulse transformer comprising:
a pulse source;
a stretcher comprising at least one first fiber Bragg grating (FBG) configured to receive input pulses from the pulse source, the stretcher having a first second-order dispersion parameter (D21);
at least one optical amplifier configured to receive pulses from the at least one first FBG; and
a compressor comprising at least one second FBG configured to receive pulses from the at least one optical amplifier, the compressor having a second second-order dispersion parameter (−D22), an absolute value of the first second-order dispersion parameter (|D21|) and an absolute value of the second second-order dispersion parameter (|−D22|) substantially equal to one another to within 10%, at least one of the stretcher and the compressor configured to be adaptively controlled,
wherein both the at least one second FBG of the compressor and the at least one first FBG of the stretcher comprise adaptively controlled FBGs.
