Abstract
Performances of photodetectors for ultrawideband systems are outlined. Among several kinds of long-wavelength photodetectors, the waveguide p-i-n photodetector has achieved the largest bandwidth-efficiency product by using two designs: a multimode waveguide and a mushroom structures. The ultrawideband high-efficiency operation of this photodiode has enabled the construction of a wide-band receiver opto-electronic integrated circuit and has made possible such novel system applications as 20-Gbit/s optical digital transmission using an Er-doped fiber amplifier and a 72-Gbit/s optoelectronic pulse-pattern generator.
