What sorts of analysis can CODE V do that apply to photonics systems?
Geometrical calculations such as simple ray tracing, spot diagrams, and encircled energy are useful in the early stages of component design. To evaluate system performance, the diffraction point spread function (PSF) is used, or more often the coupling efficiency (CEF) which is derived from the PSF. Macros allow study of CEF vs. wavelength, important for WDM systems. You can also use the beam propagation feature (BPR) to examine the amplitude and phase of a beam anywhere in the system. BPR is a powerful feature but requires careful attention to issues of sampling to get the most accurate results. Tolerance analysis is also available (see below).
