    Abstract: A system includes a pair of chassis, a housing, and a cooling module. Each chassis including multiple rails with adjacent rails defining card slots. The housing connected to the chassis in first card slots on the pair of chassis and formed to contain electronic components including a heat generating component. The cooling module connected to the chassis in second card slots on the pair of chassis and formed to contact the heat generating component through an aperture in the housing.

    Abstract: This disclosure provides planar waveguides with enhanced support and/or cooling. One or more endcaps could be disposed between coating/cladding layers at one or more ends of a core region, where the core region is doped with at least one active ion species and each endcap is not doped with any active ion species that creates substantial absorption at pump and signal wavelengths. A core region could include at least one crystal or crystalline material, and at least one cladding layer could include at least one glass. Different types of coolers could be disposed on or adjacent to different coating/cladding layers. Side claddings could be disposed on opposite sides of a planar waveguide, where the opposite sides represent longer sides of the waveguide. Endcaps and one or more coolers could be sealed to a housing, and coolant can flow through a substantially linear passageway along a length of the waveguide. One side of a planar waveguide could be uncooled.

    Abstract: An apparatus includes a heat exchanger with a body having a passage through the body. The passage defines apertures on multiple sides of the body, and the passage is configured to allow optical signals to pass through the body. One or more tapered edges are at least partially around one or more of the apertures, and each tapered edge is configured to reflect optical radiation inward into the passage. One or more absorptive surfaces are within the passage, and the one or more absorptive surfaces configured to absorb the reflected optical radiation. The heat exchanger is configured to convert the absorbed optical radiation into heat, and the body further includes one or more cooling channels configured to receive coolant that absorbs the heat.

    Abstract: A heat sink for cooling a laser gain medium includes a coolant channel, an inlet pore, an outlet pore, and a thermal optical interface (TOI) channel. The coolant channel is configured to receive a coolant for removing heat from the heat sink. The TOI channel is coupled to the coolant channel by the inlet pore and the outlet pore. The TOI channel is configured to receive a portion of the coolant through the inlet pore. The received portion forms an ultra-thin liquid TOI. The TOI channel is further configured to return a portion of the TOI through the outlet pore to the coolant channel.

    Abstract: A method is provided for operating one or more one solid-state electro-optic device to provide an electrically switching shutter. The method includes forming an alternating stack of first semiconductor layers having a first dopant and second semiconductor layers having a second dopant to form at least one superlattice semiconductor device. The method further includes applying to the at least one superlattice semiconductor device a first voltage to induce a transparent state of the alternating stack such that light is transmitted through the alternating stack, and applying to the at least one superlattice semiconductor device a second voltage different from the first voltage to induce an opaque state of the alternating stack such that light is inhibited from passing through the alternating stack.
