A data storage system including a source of heat, a substrate, a storage layer, a lubricant layer, a flying head, and a dielectric layer is disclosed. The dielectric layer is disposed between the lubricant layer and the storage layer. The flying head is disposed above the lubricant layer. The dielectric layer has a heat capacity that is sufficient to generate a temperature gradient between the storage layer and the lubricant layer so as to reduce lubricant evaporation onto the flying head.

An apparatus comprising a first reference element having an output power that varies monotonically with input frequency over an operating frequency range and receiving at least a portion of an output beam of light from an optical source. A second reference element having an output power that is frequency dependent receives at least a portion of the output beam of light. A first optical detector measures the power of a first reference beam of light from the first reference element. A second optical detector measures the power of a second reference beam of light from the second reference element. Electronic circuitry is coupled to the first and second optical detectors for receiving first and second reference signals therefrom and producing a coarse error signal for permitting coarse adjustment and a fine error signal for permitting fine adjustment of the frequency of the output beam of light.

An apparatus for filtering an input beam of light to produce an output beam of light is provided. The apparatus facilitates tuning an input beam of light to a desired wavelength by directing the input beam of light, via a mirror, onto a diffractive optical element and returning the diffracted portion of the input beam of light as an output beam of light. The apparatus may also include a polarization recovery element adapted for receiving the input beam of light and outputting a first and second spatially offset beam of polarized light. The apparatus may also be configured as a tunable receiver by utilizing a detector to detect a characteristic of a filtered output beam. The output beam may be additionally filtered by a spatial filter.

A magneto-optical (MO) data storage system has a flying optical head supported over a MO storage medium, the flying head having channels or grooves formed therein and optical elements disposed within the grooves for directing an incident light beam to the storage medium and for receiving a reflected light beam from the storage medium. The flying head may comprise a two-piece assembly comprising a slider body which flies over the surface of the storage medium, and a separate optics mounting block formed to receive the optical elements and to be supported on the flying head. Preferably, the slider body is L-shaped and provides an angled surface for receiving a micro-machined mirror aligned with optical elements on the optics mounting block and controllable for deflecting the light beam to and from the storage medium.

An optical assembly includes a light source for providing a beam of light, a lens system configured to expand and collimate the beam of light, and a configurable beam injector, wherein the beam injector contains a first grid plate and a second grid plate to block individual beams of light. The first grid plate and the second grid plate may be configured such that each grid plate respectively corresponds to particular MEMS mirrors. The grid plates can be configured to have pathways that allow for beams of light to be passed through and other pathways which are blocked to prevent the passage of light. The first grid plate and second grid plate may thus block or allow for transmission of beams of lights to those particular MEMS mirrors. The second grid plate can be configured to be easily swappable during or removable to allow for a different set of beams of light, corresponding to a different set of MEMS mirrors, to be blocked. The second grid plate can be configured to be rotated or slid linearly within a housing.

The present disclosure provides systems and methods for preventing or minimizing optical crosstalk in an optical circuit switch (“OCS”). The OCS may include a collimator lens assembly. The collimator lens assembly may include a lens array defined by a plurality of ports. Each port may include a lenslet and a spacer paired with each lenslet. Crosstalk may occur when light from other ports enter the target port's optical fiber. The collimator lens assembly may include an insert positioned relative to the lenslet. The insert may define an aperture that allows light from the target port to pass through. The insert may prevent a portion of light from adjacent ports from passing through the aperture. The insert may be located between the lenslet and spacer, on the curved surface of the lenslet, or on a plate located at a distance from the front of the lenslet.

An optical circuit switch includes a fiber hole array, a plurality of internal optical fibers, a collimating lens array, a MEMS mirror array, and a reflective surface. The fiber hole array includes an array of receptacles shaped to accept respective internal optical fibers. The collimating lens array is positioned adjacent to the fiber hole array. Each collimator of the collimating lens array optically couples light into or out of a corresponding one of the internal optical fibers. The fiber hole array, the collimator, the MEMS mirror array and the reflective surface are positioned relative to one another such that light exiting each of the internal optical fibers passes through its corresponding collimator and is redirected by a first mirror within the MEMS array towards the reflective surface, which directs the light back towards a second mirror of the MEMS mirror array, which in turn redirects the light towards a second internal optical fiber.
