  • Patent number: 10109979
    Abstract: A microelectromechanical systems (MEMS)-tunable vertical-cavity surface-emitting laser (VCSEL) in which the MEMS mirror is bonded to the active region. This allows for a separate electrostatic cavity that is outside the laser's optical resonant cavity. Moreover, the use of this cavity configuration allows the MEMS mirror to be tuned by pulling the mirror away from the active region. This reduces the risk of snap down. Moreover, since the MEMS mirror is now bonded to the active region, much wider latitude is available in the technologies that are used to fabricate the MEMS mirror. This is preferably deployed as a swept source in an optical coherence tomography (OCT) system.

  • Patent number: 8757897
    Abstract: An optical interposer includes grooves (310) for optical fiber cables (104) coupled to a transducer (120). The grooves are formed by etching a cavity (410) in a substrate (130), filling the cavity with some layer (520), then etching the layer to form the grooves. The cavity has outwardly sloped sidewalls on which mirrors (144) are later formed. The groove etch is selective not to damage the sidewalls. The groove depth is uniform due to high etch selectivity of the layer, and also because of good control over the cavity etch due to the low aspect ratio of the cavity. Electrical circuitry for connection to the transducer is fabricated after the cavity filling but before the groove etch. The cavity filling leaves the wafer planar, facilitating fabrication of the electrical circuitry. Grooves can be provided on top and bottom of the interposer. Other features are also provided.

  • Patent number: 8702317
    Abstract: An optical connector having an optical fiber inserted into a connector main body includes a buckling regulating section whose length in an optical fiber insertion direction is formed variable and which regulates a buckling of the optical fiber while becoming short in an optical fiber insertion direction when the optical fiber is inserted into the connector main body. Even if an insertion area is made long, since no buckling of the optical fiber is generated, the buckling regulating section can sufficiently increase an insertion force of the optical fiber. Thus, even when foreign substances such as dusts enter and an insertion resistance increases, the optical fiber can be securely inserted. Further, the buckling regulating section is very advantageous to realize an end surface preparation of the optical fiber making use of the insertion force of the optical fiber such as a coating removing of the optical fiber, and an end surface grinding preparation of the optical fiber.
