Title: Optical dispersion compensator and optical pulse generator and optical communication system using the compensator
Inventor: RI EIKON
IPC: G02B6/00
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To provide a microminiature, inexpensive and stable optical dispersion compensator capable of dispersing and compensating light pulses of 100 femtosecond order of a wide spectral width by allowing the spread of pulse time width and waveform deterioration to transmit a resonator consisting of multilayered dielectric films. SOLUTION: Spacer layers 2 consisting of AlGaAs layers are grown by an org. metal vapor growth method on an n type GaAs substrate 1. Next, the periodically multilayered dielectric films 5 are formed by laminating GaAs high-refractive index layers 3 and AlAs low-refractive index layers 4 at 9.5 periods thereon. Namely, the multilayered films 5 are formed by alternately laminating n-layers of the low-refractive index layers 4 and (n+1) layers of the high-refractive index layers 3 in the transmitting direction of the light pulses, in such a manner that the high-refractive index layers 3 exist at both ends.  The spectral width of the transmission regions adjacent to the high-reflection regions of the resonator structure is made wider to enhance the dispersion effect of the transmission regions by adopting the resonator structure formed of the multilayered dielectric films 5 to the optical dispersion compensator, by which the dispersion compensation of the light pulses from 100 femtoseconds to 10 picoseconds is made possible.
