摘要:
A method and system for spot size selection wherein an indication of a spot size selection is received and a spot size is generated corresponding to the spot size selection by propagating an optical signal via one of the claddings of a dual-clad optical fiber. The system for spot size selection includes a plurality of lens arrays, at least one galvanometer, and a plurality of dual-clad fibers to propagate an optical signal from one of the plurality of lens arrays.

摘要:
Die Erfindung betrifft einen asphärischen Faserkollimator (1) mit einem Eingang (1.1) zur Einspeisung von Licht aus einer optischen Faser und einem Ausgang (1.2) zur Abgabe von entlang einer in Längsrichtung angeordneten optischen Achse (A) kollimiertem Licht, umfassend ein fokussierendes asphärisches rundoptisches Element (2), dessen Brennpunkt (F) eingangsseitig auf der optischen Achse (A) liegt, und eine Faseraufnahme (4) zur Aufnahme der optischen Faser derart, dass die Austrittsfläche der optischen Faser senkrecht zur optischen Achse liegt und den Brennpunkt (F) des asphärischen rundoptischen Elements (2) umfasst. Der Öffnungswinkel (α) des fokussierenden asphärischen rundoptischen Elements (2) ist mindestens so groß gewählt, dass (1 - 3⋅10 -13 ) ⋅100 Prozent der aus der optischen Faser austretenden Strahlungsenergie in den Öffnungswinkel (α) fallen.
摘要:
An optical device includes: (1) a substrate; and (2) multiple meta-lenses disposed on the substrate, each meta-lens of the meta-lenses including multiple nanofins disposed on a respective region of the substrate, the nanofins together specifying a phase profile of the meta-lens.

An optical interface device for a photonic integrated system includes a plug and a receptacle. The receptacle is operably arranged on a PIC that supports waveguides. The plug operably supports optical fibers. The receptacle and plug are configured to operably engage to establish optical communication between the optical fibers and the waveguides. A tab on the receptacle is configured to constrain longitudinal motion while allowing for lateral motion of the receptacle to adjust its position relative to the PIC to optimize alignment. The plug can include a spacer sized to fit within a recess defined by the tab to further facilitate alignment. The receptacle and plug can be engaged and disengaged in a manner similar to conventional electrical connectors.

A beam-shaping optical system includes a sheath defining a central cavity having an inner wall, an optical fiber positioned within the cavity and engaged with the inner wall of the sheath, and a beam-shaping insert positioned within the sheath and engaged with the inner wall of the sheath. The beam-shaping insert includes a beam-shaping element with a reflective element aligned with an optical axis of the optical fiber. The optical fiber is configured to emit an electromagnetic beam toward the beam-shaping element and the beam-shaping element is configured to reflect the electromagnetic beam externally to the beam-shaping insert.
