1064 nm 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
- 1064 nm band is defined as 1055 nm – 1085 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
Product Overview
While we primarily supply PING gratings as OEM products, the following selection of gratings are stock available. You can order the gratings below online, or request a quotation on these or customized gratings.
| Grating | Resolution | AOI | Grating area | Chip size | DE (*) | PDL |
|---|---|---|---|---|---|---|
| PING-1379-422 | 1379 l/mm | 45° | 20 mm x 15 mm | 22 mm x 17 mm | >94% | <0.25 dB |
(*) Note: DE is minimum absolute diffraction efficiency across both polarizations and the wavelength range
