摘要： A method for assembling a fiber mount to a base, comprising: placing metal spacers and solder between the fiber mount and the base, applying a squeezing force with a configured time, thus providing a precise control of the gap between the fiber mount and the base, thereby preventing the solder from cracking and reducing the impact of solder creep.

摘要： An optical device may include an optical fiber having an input leg and an output leg, a collimating lens, and an optical isolator core positioned between the optical fiber and the collimating lens. The optical isolator core may include birefringent crystals, a Faraday rotator, a halfwave plate, and/or the like. The optical isolator core may laterally displace a portion of a light beam. In some implementations, the optical isolator core may be a single stage isolator core, a dual stage isolator core, and/or the like. The optical device may include a wavelength-division multiplexing filter, another collimating lens, and a pump chip.

摘要： An optical device (100) including a base (305, 406) with a first coefficient of thermal expansion. The optical device (100) may include an opto-mechanical component (310, 402) with a second CTE attached to a surface of the base (305, 406) via a solder layer (126, 315, 404). The first CTE and the second CTE may differ by greater than a threshold amount. A spacer (128, 320, 408) may be disposed within the solder layer (126, 315, 404) to attach the opto-mechanical component (310, 402) to the base (305, 406).

摘要： An optical isolator core (110) includes a Faraday rotator (112) and a plurality of birefringent crystal plates (114). The plurality of birefringent crystal plates (114) may include a first birefringent crystal plate (114-1) to separate input light into light having a first polarization and light having a second polarization, and a second birefringent crystal plate (114-2) to combine the light having the first polarization and the light having the second polarization in output light that is laterally displaced by the single stage optical isolator. The Faraday rotator (112) may be provided between the first birefringent crystal plate (114-1) and the second birefringent crystal plate (114-2). The plurality of birefringent crystal plates (114) further include a third birefringent crystal plate (114-3) provided between the Faraday rotator (112) and the second birefringent crystal plate (114-2). Additionally, or alternatively, the optical isolator core (110) may further include a half-wave plate (116) arranged between the Faraday rotator (112) and the first birefringent crystal plate (114-1).
