FORFARANDE JEMTE ANORDNING ATT OKA BANDBREDDEN I EN HOGHASTIGHETSMODULATOR |
摘要 |
A method of increasing the available bandwidth of a high speed modulator in which an optical signal is modulated by a microwave signal (v) along an interaction distance (L). After passing half the interaction distance (L/2) the modulating signal is pole reversed by a positive (+E) and a negative (-E) bias voltage being connected to two different sections of the interaction distance. An apparatus according the method in an optical directional coupler modulator is described. |
