Dynamic range alignment tolerant optical coupling for fiber optic communications

摘要

In one exemplary embodiment, an optical coupler of a fiber optic system can include a light-source input cavity packaged in an outer casing. The cavity can receive an optical signal from a light source. An optical collimator packaged in the outer casing such that a receiving end of the optical collimator can receive the light source from the light-source input cavity. The optical collimator can include at least one beam forming stage. The optical collimator can generate a collimated beam output from the optical signal. An optical cavity can receive the collimated beam output of the optical collimator. The optical cavity can be coaxially included in a receiving optical fiber coupled with the outer casing coupled with optical cavity. The optical cavity can receive the collimated beam output of the optical collimator and input the collimated beam into the receiving optical fiber.
