Document Type and Number:
Japanese Patent JPH06507258
Kind Code:
A
Abstract:
This invention discloses a method and apparatus for shortening the length of a pulse of light. Generally, the method entails altering the index of refraction of an optical medium (14) through which the pulse of light is traveling at an area of the medium (14) where the front end of the pulse of light is located, such that the front end of the pulse of light travels slower than the back end, thus enabling the back end to catch up with the front end in order to shorten the length of the pulse. To accomplish this, it is proposed to generate an electric field across the optical medium (14) by a charge carrying medium (12) positioned relative to the optical medium (14), such that the index of refraction is altered by the electro-optic effect. In addition, it is possible to alter the index of refraction of the optical medium (14) by surrounding the optical medium (14) with a piezoelectric material (20) and applying an electric field to the piezoelectric material (20) such that the piezoelectric material (20) compresses the optical medium (14), thus altering the index of refraction.
