Generation of lossy mode resonances in a broadband range with multilayer coated coverslips optimized for humidity sensing

Coverslips deposited with a metallic oxide can be employed for generating lossy mode resonances by lateral incidence of light on the coverslip. Here it is demonstrated that with copper oxide the fading observed with other materials in the near infrared (NIR) wavelength range is avoided and LMRs can...
