What is A Tandem Approach to Fabricate a Hybrid, Organic‐Add‐Drop Filter Using Single‐Crystal Disk‐Resonators and Pseudo‐Plastic Crystal Waveguides about?

## Abstract The progress of photonic integrated circuits (PICs) and related nanophotonic technologies is greatly influenced by precise and complex circuit fabrication know‐how. The integration of chemically different, multiple optical components for constructing hybrid PICs is a tedious and costly affair. Herein, a novel approach to construct a key optical circuit component is reported, namely a hybrid organic add‐drop filter (HOADF) by tandem use of two different techniques, namely, mechanophotonics (micromechanical manipulation) and crystal photonics foundry (focused ion beam, FIB‐assisted crystal milling). The successful integration of FIB‐milled, yellow‐emissive, perylene disk resonators (DRs) to two chemically different pseudo‐plastic microcrystal waveguides, namely yellow–orange‐emitting (Z)−2‐(3,5‐bis(trifluoromethyl)phenyl)−3‐(7‐methoxybenzo[c][1,2,5]thiadiazol‐4‐yl)acrylonitrile (BTD2CF3) and green‐emitting (E)−1‐(((5‐bromopyridin‐2‐yl)imino)methyl)naphthalen‐2‐ol (BPyIN), provides a three‐component HOADF. The fabricated HOADF produce, split, route light signals of different wavelengths in a controlled fashion as anticipated from the circuit geometry. This presented innova
