摘要： A pump laser package (650) may include an input fiber (205) to send signal light on a first optical path inside a package, a source (215) to send pump light on a second optical path inside the package, and an output fiber (210) on a third optical path inside the package. The pump laser package(650) may include a WDM filter inside the package to receive the signal light on the first optical path and send the signal light on the third optical path, and receive the pump light on the second optical path and send the pump light on the third optical path. The pump laser package (650) may include an isolator (405) inside the package to transmit the signal light in a first direction, and block the signal light in a second direction, or a photo-diode (510) to receive a portion of the signal light sent on a fourth optical path.

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 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).
