Telecom O-band gratings

PING – Polarization independent (low PDL) gratings for telecom O-band
 

Main characteristics:

  • Fused silica transmission gratings
  • Production technology: Holostepper (Holographic stepper) and RIE etching
  • O-band is defined as 1274 nm – 1346 nm (but can be OEM customized)
  • 100% dielectric materials – No polymers, epoxies, gelatins or metals
  • Grating chip thickness: 0.625 mm
  • Operating temperature at least 500° C
  • Packaging: Packed in semiconductor grade Gelpak containers, sealed in class 10 cleanroom
