How this tool works
A device-oriented bridge from photon quantities to practical optical sources, fibers, detectors, and resonators.
All quantitative graphs carry explicit units on both axes.
Core equations
E = hc/λzR = πw₀²/λNA = √(ncore²−nclad²)Prx(dBm)=Ptx−Σ lossesFSR=c/(2nL)Assumptions
- Gaussian-beam calculations use an ideal TEM00 beam.
- Fiber mode count uses the weak-guidance step-index approximation.
- Cavity finesse assumes equal mirror reflectivity and negligible internal loss.
Limitations
- These calculators do not replace component datasheets, optical design software, or laser safety analysis.
