英文摘要	This invention embodies an optical device with a Fabry-Perot cavityformed by two reflective mirrors and an active layer which is doped with a rare earthelement selected from lanthanide series elements with number 57 through 7 Thethickness of the active layer being a whole number multiple of .lambda./2 wherein .lambda. is theoperating, or emissive, wavelength of the device, said whole number being one ofthe numbers ranging from 1 to 5, the fundamental mode of the cavity being inresonance with the emission wavelength of said selected rare earth element, Cavity-quality factors exceeding Q = 300 and finesses of 73 are achieved with structuresconsisting of two Si/SiO2 distributed Bragg reflector (DBR) mirrors and an Er-implanted (.lambda./2) SiO2 active region. The bottom DBR mirror consists of four pairsand the upper DBR mirror consists of two-and-a half pairs of quarterwave (.lambda./4)layers of Si and SiO2. Photoluminescence at room temperature reveals a drasticenhancement of the luminescence intensity of the cavity emitted along the opticalaxis of the cavity versus the luminescence without the top mirror. The luminescenceintensity of the cavity is typically 1-2 orders of magnitudes higher as compared tostructures without a cavity. Furthermore, since the emission wavelength and theintensity decrease for off-normal emission angles, the change in emissionwavelength can be quantitatively described by assuming that the on-axis componentof the optical wave is resonant with the cavity.
