The optical gain and differential gain showed a more rapid increase as a function of the injected carriers as temperature decreased. The alpha-factor for the lasing mode was estimated as 2.8 at room temperature and decreased to a value as low as 0.6 at 80 K. (C) 2009 Optical Society of AmericaItem type:Item, A continuously tunable and filterless optical millimeter-wave generation via frequency octupling(2009-10-26) ;Lin, Chun-Ting ;Shih, Po-Tsung ;Jiang, Wen-Jr ;Chen, Jason (Jyehong)Peng, Peng-ChunThis work proposes a cost-effective, continuously tunable and filterless optical millimeter-wave (MMW) signal generation employing frequency octupling. Optical MMW signals with 30-dB undesired sideband suppression ratios can be obtained. Since no optical filtering is required, the proposed system can be readily implemented in wavelength-division-multiplexing (WDM) systems. V-band 60-GHz and W-band 80-GHz optical MMW signals are experimentally demonstrated. Because of the high undesired sideband suppression ratio, 60-GHz waveform with 50% duty cycle is observed. The single-sideband (SSB) phase noise of the generated 60-GHz signal is -73 dBc/Hz at 10 kHz. The proposed system is a viable solution for the future ultra-high frequency MMW applications up to 320 GHz using the external modulator with a limited bandwidth of 40 GHz. (C) 2009 Optical Society of AmericaItem type:Item, Full duplex 60-GHz RoF link employing tandem single sideband modulation scheme and high spectral efficiency modulation format(2009-10-26) ;Shih, Po-Tsung ;Lin, Chun-Ting ;Jiang, Wen-Jr ;Chen, Yu-HungChen, Jason (Jyehong)This study proposes a full duplex 60-GHz band radio-over-fiber (RoF) link using a modified tandem single sideband (TSSB) modulation scheme with frequency doubling. Based on the modified TSSB modulation scheme, no dispersion induced fading is observed; high spectral efficiency vector signal can be utilized; and wavelength reuse can also be achieved. Both single carrier 8-QAM and QPSK-OFDM signals for down-link transmissions are experimentally demonstrated. After transmission of 50-km SSMF, no significant receiver power penalties are observed. Wavelength reuses with 1.25-Gb/s OOK using a reflective semiconductor optical amplifier (RSOA) for up-link transmission are also demonstrated. After transmission of 50-km SSMF, no significant receiver power penalties are also observed. (c) 2009 Optical Society of America
