Abstract :
A new 1.3/1.55 μm WDM/photodiode(PD) module has been designed and fabricated for use in optical access networks. A 1.3 μm-PD and a 1.55 μm-PD were arranged in series along the optical axis in a coaxial package. The 1.3 μm-PD with an In0.66Ga0.34 As0.76P0.24 photosensitive layer (λ g=1.42 μm) absorbs 1.3 μm digital optical signals and it is transparent to 1.55 μm wavelength. The 1.55 μm-PD with an In 0.53Ga0.47As photosensitive layer absorbs 1.55 μm analog optical signals. Responsivity of the module is 0.82 A/W at 1.31 μm wavelength and 0.75 A/W at 1.55 μm wavelength, respectively. IMD2 of the 1.55 μm-PD measured by two-tone method was -76.1 dBc at Pf(1.55 μm) of -6 dBm. Bit error rate (BER) of the 1.3 μm-PD was measured at 28.8 Mb/s by using an amplifier with bandwidth of 200 MHz and was found to be less than 10-8 at Pf(1.3 μm) of -30 dBm
