  • Publication number: 20230305227
    Abstract: A thermal compensator, for use in connection with arrayed waveguide grating (AWG) modules which are, in turn, utilized in conjunction with wavelength multiplexing and de-multiplexing within optical networks, is disclosed. The thermal compensator comprises a bow-shaped frame member and a central bar member. The bow-shaped frame member is characterized by a higher coefficient of thermal expansion than that of the central bar member such that the bow-shaped frame member can expand and contract at variable rates compared to that of the central bar member under certain temperature conditions. The bow-shaped frame member is adapted to be attached to a movable section of an athermal arrayed waveguide grating (AAWG) module such that the expansion and contraction movements of the bow-shaped member influence the movement of a movable section of the AAWG module in order to maintain the proper focus of the AAWG module across disparate temperature conditions.

  • Patent number: 10007130
    Abstract: Systems, methods, and apparatus for optical switching. In some implementations, a magneto-optic switch includes multiple optical components positioned in order along a light path including: a single fiber optical collimator, a first birefringent optic crystal, a first half wave plate assembly, a polarization rotation assembly, a second half wave plate assembly, a second birefringent optic crystal, and a dual fiber optic collimator, wherein a first side of the polarization rotation assembly near the first half wave plate assembly includes a first Faraday rotator element, a second side of the polarization rotation assembly near the second half wave plate assembly includes an optic rotation component, the polarization rotation assembly having a magnetic field generating component outside the first Faraday rotator element.

  • Patent number: 9519103
    Abstract: Athermal arrayed waveguide grating wavelength division multiplexers applicable to a relatively wide temperature range. One athermal arrayed waveguide grating wavelength division multiplexer includes a base board including an arrayed waveguide grating chip, wherein the base board and the arrayed waveguide grating chip are divided into a first portion and a second portion through at least one division plane; and a sliding deflection component positioned on the base board including a first end and a second end which are respectively fixed on the first portion and the second portion, the sliding deflection component including: a telescopic rod having a length that changes with temperature variation, a first sidewall and a second sidewall positioned at two ends of the telescopic rod, respectively, and a first deflection limiting piece fixed on one side of the telescopic rod.
