Free-space Isolators

Free-space isolators are single stage isolators designed using polarizer optics and half-waveplate retarders. Both crystals are grown, polished and coated in-house to provide industry leading performance at a very low cost.

Features

  • High isolation
  • Low insertion loss
  • Compact size

Applications

  • Suppression of optical back reflection in transmitters
  • Suppression of optical back reflection in pump lasers
Hybrid Devices

Hybrid components are integrated multi-function devices that reduce cost and save space. II-VI offers various types of hybrid components including WDM+ Isolator, GFF+ Isolator, Tap+ Isolator, Tap + Isolator + GFF, Tap + PD. Other custom hybrid components are also available upon request.

Features

  • Compact design
  • Optimum performance of combined functionality
  • Lower cost of combined functionality

Applications

  • DWDM amplifiers
  • Single channel amplifiers
  • ROADM systems
Optical Circulators

Optical circulators route an optical signal from an input port to an output port in a non-reciprocal manner. For example, in a 3-port circulator a signal entering Port 1 will exit Port 2, a signal entering Port 2 will exit Port 3 and a signal entering Port 3 will exit Port 1. Circulators are available in 3- or 4-port configurations.

Features

  • Low 5.5 mm diameter profile
  • Low insertion loss
  • Available housed in 3- or 4-port configuration

Applications

  • Fiber Bragg grating applications
  • Tunable dispersion compensators
Polarization Maintaining Coupler

Polarization maintaining couplers are now available from II-VI in a small micro-optics packaging format in addition to the cylindrical format. The small micro-optics package is ideal for integration in small form-factor pluggable transceivers such as the CFP, CFP2 and CFP4 line side transceivers.

Features

  • High polarization extinction ratio
  • Low insertion loss
  • High directivity

Applications

  • Coherent transceivers
  • Optical amplifiers
  • Power monitoring
