A strong sum frequency generation (SFG) has been demonstrated using two cavity modes realized in a GaAs/AlAs coupled multilayer structure which GaAs half-wavelength layers are by an intermediate distributed Bragg reflector multilayer. The was grown on (113)B substrate molecular beam epitaxy. Two with optical difference of 3.3 THz were clearly observed at 1514 and 1540 nm the reflection spectrum. room-temperature SFG second-harmonic (SHG) signals measured simultaneous excitation 100 fs laser pulses. peak intensity signal more than 400 times larger that SHG from alone, indicating effective second-order nonlinearity strongly enhanced effect.
