US 11,693,266 B2 · Glue free Faraday isolator

Abstract

A glueless optical device includes a housing having a first optical portal and a second optical portal opposite the first optical portal. A first optical component is within the housing adjacent to the first optical portal, and a second optical component is within the housing adjacent to the second optical portal. A central optical component is positioned within the housing between the first optical component and the second optical component. A first holder is configured to mount the first optical component to the housing via a first plate spring, and a second holder is configured to mount the second optical component to the housing via a second plate spring. A construct having a coil spring at least partially wrapped around a cylindrical crystal is configured to pass through a bore hole in the central optical component and mount the central optical component between the first holder and the second holder.

Dependent claims

A glueless optical device comprising;

a housing comprising a first optical portal and a second optical portal opposite the first optical portal;
and
a Faraday rotator disposed within the housing, the Faraday rotator comprising a magnetics portion with an axial bore hole through the magnetics portion, the axial bore hole being configured to convey light to and/or from the first optical portal and to and/or from the second optical portal, the Faraday rotator further comprising a construct disposed within the axial bore hole of the magnetics portion, the construct comprising:
a first tubular spring;
and
an optical crystal disposed between the first tubular spring and the second optical portal,
wherein the construct is arranged in an optical pathway between the first optical portal and the second optical portal so the optical pathway proceeds through a first axial gap within the first tubular spring and through the optical crystal.
