Cumulative publication trends in photonics subtopics from the Scopus database. The stacked area plot shows the annual growth in paper counts from 2000 onward.

Description

The script queries Scopus by building flexible TITLE-ABS-KEY clauses for each photonics topic, incorporating exact phrases, hyphenated variants, proximity searches (words within 3 positions), and plural forms to catch variations like "photonic inverse design" or "inverse-designed". It adds subject area filters (physics, engineering, materials, biology, medicine) and publication year to narrow results. For each topic and year from 2000-2024, it makes an API call to Scopus using the provided key and retrieves the total paper count.
