Fundamentals of Photonics
==========================

This collection provides worked solutions for every boxed exercise and every
end-of-chapter problem in Bahaa E. A. Saleh and Malvin Carl Teich,
*Fundamentals of Photonics*, second edition.  Prompts are paraphrased rather
than reproduced.  The inventory contains 131 in-text exercises and 314
end-of-chapter problems, for 445 worked items across all 24 chapters.

Numerical exercises retain the supplied values and show the governing
equation, substitution, and result.  Analytical and design questions show the
decisive derivation or a reproducible construction.  When a question asks for
a graph or numerical experiment, the solution specifies the function,
parameters, and check needed to reproduce it.

Each solution defines its local notation, names and links the mathematical
identities it uses, shows numbered working where equations are involved, and
ends with a verification.  The shared formula catalogue is available here:

All 131 boxed in-text exercises use an illustrated step-by-step presentation
and carry stable labels from **Figure 1** through **Figure 131**. Exercise
1.1-1 has a fully labeled geometrical construction; the remaining 130 use a
topic-specific SVG calculation map showing the inputs, physical model,
output, variable legend, and independent check. Every symbol retained in a
legend is also placed on the illustrated model. End-of-chapter problems
retain the compact structured presentation.
