摘要： In a pipe structure in which an optical fiber passes, miniaturization of the optical module in the longitudinal direction of the optical fiber is prevented. In the optical module according to the present invention, a holding structure of the optical fiber necessary to adopt the pipe structure is moved to a cover extension unit of the package. The optical fiber is adhered and fixed to the cover extension unit protruding from the cover body unit of the package to ensure protection of the optical fiber, and the optical waveguide chip is disposed to be closer to an inner wall of a side surface of the package. By disposing the optical waveguide chip to be close to the inner wall of the package as much as possible and reducing the mounting area in the package to the utmost, it is possible to realize miniaturization of the entire optical module.

摘要： A polarization modulation method of photonic pulses, in particular for generating quantum cryptographic keys, ensures an optimum stability of the outgoing polarization states, and comprises the steps of: generating a plurality of photonic pulses with an unspecified polarization state obtained by the overlapping of both the horizontal and vertical polarization modes thereof, and routing them in a first polarization-maintaining fiber; splitting said horizontal and vertical polarization modes and routing them in respective terminals of a second polarization-maintaining fiber forming a ring, whereby they travel such ring clockwise and counter-clockwise respectively, or vice versa; inducing a respective phase modulation (oe, ol) of both said polarization modes, in one point of said ring which is spaced from said terminals by optical paths having different length along said ring, thereby a polarization-maintaining fiber delay line is determined; and recombining said polarization modes in one single photonic pulse beam, and routing the resulting beam through said first polarization-maintaining fiber, by obtaining, at the output thereof, a polarization state of the pulses depending upon the difference between said phase modulations (oe, ol).
