摘要： A symmetric distributed feedback (DFB) laser that is integrated in a silicon based photonic integrated circuit can output light from both sides of the symmetric DFB laser onto waveguides. The light in the waveguides can be phase adjusted and combined using an optical coupler. The symmetric DFB laser can generate light and symmetrically output light onto different lanes of a multi-lane transmitter.

摘要： A receptacle (6) includes an optical fiber stub (7). A lens (5) includes an incident-side curved surface (9), an emission-side curved surface (10), and a barrel (11) provided between the incident-side curved surface (9) and the emission-side curved surface (10). A receptacle holder (8) holds the receptacle (6) so that the lens (5) and the optical fiber stub (7) are not in contact but separated from each other. When light out from the optical fiber stub (7) enters the lens (5) through the incident-side curved surface (9), the light is condensed inside the lens (5) and then spreads again, and the light out from the emission-side curved surface (10) is condensed onto a light-receiving surface of the light-receiving device (2).

摘要： An optical logic gate decision-making circuit that combines non-linear materials, such as silicon nitride, on a silicon-on-insulator (SOI) substrate is described. Circuitry includes a ring cavity coupled to an input optical bus waveguide. The input optical bus waveguide receives an optical signal and passes the optical signal to the ring cavity. An electro-optical device, for instance a PN junction, is integrated within the ring cavity to modulate the optical signal such that an optical logic gate function is enabled. An output optical bus waveguide is also coupled to the ring cavity, which outputs the optical signal modified based on the optical logic gate function and based on a wavelength routing function. By using silicon nitride, the optical non-linearity of the materials enables an “all-optical” logic gate. Thus, the optical logic gate decision-making circuit is suitable for all-optical circuits, and support ultrafast optical signal processing and enabling packet switching of data.

摘要： A MEMS based alignment technology based on mounting an optical component on a released micromechanical lever configuration that uses multiple flexures rather than a single spring. The optical component may be a lens. The use of multiple flexures may reduce coupling between lens rotation and lens translation, and reduce effects of lever handle warping on lens position. The device can be optimized for various geometries.

摘要： Light that returns through reflection from the optical connection portion between a semiconductor optical waveguide and an optically functional element is reduced through the use of a simplified structure in a semiconductor optical waveguide device. The device is provided with an anti-reflection diffraction grating having the period to prevent light that has been led through the semiconductor optical waveguide towards the portion connected to the optically functional element from being reflected in the direction from which the light has been led.

摘要： Disclosed herein is a high speed optical transceiver module, which makes it possible to prevent a wavelength shift and thus to achieve low power and high efficiency by forming a hole with a predetermined depth in a stem heat sink for dissipating heat generated in an LD through a lower portion of a stem and putting a micro heater in the hole, thereby compensating for the temperature of the LD in order to prevent wavelength shift caused by the influence of the ambient temperature on an LD chip in a transistor outline (TO) when an un-cooled optical transceiver module is driven at low temperature and to prevent the communication from being impossible when the ambient temperature is lowered during the communication using a CWDM scheme.
