Abstract
An optical code division multiplexing signal generator provided with an optical pulse light source, a first encoder to an Nencoder, a first optical modulator to an Noptical modulator, and a first optical circulator to an Noptical circulator. The first optical circulator inputs an input optical pulse train to a first encoder, and inputs a first encoded optical pulse train output by Bragg reflection from the first encoder to the first optical modulator. The koptical circulator inputs an input (k−1)optical pulse train which has passed through the (k−1)encoder to a kencoder, and inputs a kencoded optical pulse train output by Bragg reflection from the kencoder to the koptical modulator. Herein k takes all integers from 2 to N, and N is a positive integer of 2 or more.
