    Abstract: A circuit arrangement is provided for allowing the bidirectional exchange of received and transmitted signals over a single monomodal optical fiber. The light transmitter (usually a laser or a LED), the receiver of optical signals and an optical system suitable for directing the optical signal to be transmitted to the monomodal optical fiber ad for directing the optical signal from the monomodal optical fiber to the receiver collects the signals in one passage. The optical system uses an optical transceiver employing a light transmitter and a light receiver. This optical transceiver is formed in a unitary housing. The optical system includes first and second lenses which may be graded-index waveguide sections and a planar filter disposed therebetween, the planar filter typically being an interferential filter. The optical system is formed on a support which allows the light transmitter which is typically a laser to be disposed directly adjacent one of the lenses. The surface of the lens abutting the optical communication fiber and optical stub is angled with respect to perpendicular to the axis of the symmetry of the optical system to prevent reflected optical power from entering the light transmitter, particularly when it is a laser, hereby reducing noise and instability within the laser source.

    Abstract: An optical device is formed by a first chip and a second chip bonded together. The first chip (4 has an optical layer of glass housing an optical circuit; the second chip has a body of semiconductor material housing integrated electronic components and coated with a bonding layer of glass fixed directly and contiguous to the optical layer of the first chip. The bonding layer delimits cavities facing corresponding cavities in the first chip in positions corresponding to the intersection points of waveguides constituting the optical circuit. The cavities are filled with a liquid having the same refractive index as the waveguides. Underneath each cavity, in the body of semiconductor material there is present a resistor, which, when traversed by current, causes formation of a bubble inside the chamber and deflection of the light beam traversing a waveguide towards a different waveguide.

    Abstract: In order to provide an end face of an optical fiber with a spherical curvature of predetermined radius, designed to optimize the transfer of luminous intensity from an adjoining light source such as a light-emitting diode, a flat fiber is heated to a temperature near its melting point while its profile is optically enlarged. When that profile is found to have reached a predetermined shape criterion, as determined by visual observation or by electronic scanning, heating is terminated.
