Three ways in
A few design parameters are enough to compute; a complete measurement record buys a review-grade certificate.
A · free
Fill it yourself
Download the budget or component sheet, fill it in, see the effective squeezing and the bottleneck.
For a first look.
B · single
Verify one link
Send the parameters; we compute, re-check and issue. One-page verdict in three working days.
Before design freeze, a bid, or submission.
C · project
Alongside the design
Join by round: split the budget, set tolerances, recompute after each change, one convention throughout.
For specs decomposed to components and revised often.
What to prepare
No layouts, code or process detail. Anything missing is stated in the certificate.
| Item | Need | If missing |
|---|---|---|
| Input squeezing r | Required | Certificate marked "terminal value only" |
| Loss per stage | Required | Design values accepted, marked as such |
| Added noise n | Recommended | Computed as 0 and noted |
| Wavelength and mode field | Recommended | Geometric terms measured or estimated |
| Target | Optional | Status only, no inverse solve |
