We have successfully investigated the use of a whispering gallery mode (WGM) optical micro-bottle resonator (MBR) for liquid formaldehyde (CH 2 O) sensing. The MBR was fabricated via the “soften-and-compress” method to create a bulge (bottle) structure with a bottle diameter of 190 μm. The MBR was o...
