Tunable harmonic intensities based on an elector-absorption modulator (EAM) are presented. The configuration is based on a Sagnac loop interferometer containing an elector-absorption modulator (EAM). Signal responses are obtained by modulating the clockwise and counterclockwise propagating waves inside the Sagnac loop. Measured results verify the theoretical expressions and demonstrate continuously tunable ability of amplitude for fundamental and harmonic terms. Frequency doubled and tripled electrical signals are also demonstrated.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
