Chirp measurement
WebThe term “chirp” is sometimes also used in another context, when the instantaneous temporal or spatial frequency of some quantities other than the electric field varies. This can occur, e.g., in fiber Bragg gratings with … Webtemporal chirp measurement techniques are either direct or indirect and they are based on the pulse response of laser diodes. The direct techniques are easier but require a fast detector and rely on a reasonable estimate of the pulse shape. Key Words: Frequency …
