An optical coupled-resonator may simulate the phenomenon of electromagnetically induced transparency (EIT) in atomic vapors. We utilize the separated optical cavity mirrors to set up the coupled-resonator, which is easy to adjust the parameters of optical coupled-resonator. The reflection spectra of the coupled-resonator with the middle cavity mirror of different transmittance are measured. The EIT-like effect is observed in the optical coupled-resonator due to the classical destructive interference. This system can be used to study the slow and fast light experiments due to its simplicity and flexibility.
