   Abstract:
   A multimode, Mach-Zehnder, chem/bio sensor with sensitivity developed through modal pattern analysis is demonstrated on silicon. Simulated and experimental data show that waveguide structures less than 5000-μm enable fully-integrated sensors with index sensitivities near 3×10^-6 and methanol-in-vapor sensitivities near 250 parts-per-billion vapor (ppbv)
