1. An optical device, comprising:
an optical fiber;
a solder material; and
a fibermount comprising a non-porous material, the optical fiber being affixed to the fibermount by the solder material,
wherein the non-porous material of the fibermount has a thermal conductivity of less than 20 Watts per meter-Kelvin (W/m−K),
wherein a coefficient of thermal expansion (CTE) of the non-porous material of the fibermount matches a CTE of the solder material, and
wherein the CTE of the non-porous material of the fibermount matches a CTE of a material of the optical fiber.
