980 nm Pump Lasers – Single Chip

II-VI Photonics offers a variety of single-chip pump lasers addressing all areas of low noise all-optical amplification and power consumption requirements. Increasingly, network providers are concerned with component density and power consumption which translates into cost of installation and cost of ownership of a network. To address this, II-VI Photonics offers a suite of 980 nm pump lasers from uncooled, semi-cooled and traditional-cooled pumps over a set of market leading power ranges.

980/1550 WDM couplers

WDM couplers are passive optical components that are used to combine a 980 nm pump laser source with a DWDM signal in the C-band (around 1550 nm). WDM couplers are manufactured using proven fused biconic fiber technology. Tap couplers and splitters are also available using the same technology.

 

 

Features

  • High reliability performance
  • Low cost

Applications

  • DWDM amplifiers
  • Single-channel amplifiers

 

Gain Flattening Filters

Gain flattening filters (GFF) are designed with an insertion loss profile that exactly matches the inverse of an optical amplifier gain ripple profile so as to flatten the spectral output of optical amplifiers. These GFF devices provide a high degree of matching to most custom target insertion loss profiles thus greatly minimizing residual ripple in the optical amplifier system, which ultimately improves system margin and therefore increases transmission reach.

 

 

Features

  • Wide-band, C & L-bands
  • Exceptional thermal stability
  • Low chromatic dispersion
  • Compact size

Applications

  • EDFAs
  • Raman amplifiers

 

Optical Isolators

An optical isolator is a nonreciprocal transmitting optical passive component that allows light to go in one direction based on the Faraday Effect. Several types of isolators are available including single-stage, dual-stage, mini-size, 2-in-1 and polarization maintaining isolators.

 

 

Features

  • One-stop source for a wide variety of Isolators
  • Lowest cost & high performance guaranteed
  • Compact size: 3.0×23 mm
  • Low PMD & low loss

Applications

  • EDFAs
  • Transceivers

 

Hybrid Devices

Hybrid components are integrated multi-function devices that reduce cost and save space. II-VI Photonics 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
