Journal ArticleDOI
High-speed and high-output InP-InGaAs unitraveling-carrier photodiodes
TL;DR: The unitraveling-carrier photodiode (UTC-PD) as mentioned in this paper utilizes only electrons as the active carriers, which is the key for its ability to achieve excellent high-speed and high-output characteristics simultaneously.
Journal ArticleDOI
120-GHz-band millimeter-wave photonic wireless link for 10-Gb/s data transmission
Akihiko Hirata,Toshihiko Kosugi,Hiroyuki Takahashi,R. Yamaguchi,Nakajima Fumito,Tomofumi Furuta,Hiroshi Ito,H. Sugahara,Yasuhiro Sato,Tadao Nagatsuma +9 more
TL;DR: In this article, a 120-GHz-band wireless link that uses millimeter-wave photonic techniques was developed, which achieved error-free transmission of OC-192 and 10-GbE signals over a distance of more than 200 m with a received power of below -30 dBm.
Journal ArticleDOI
InP/InGaAs uni-travelling-carrier photodiode with 310 GHz bandwidth
TL;DR: In this paper, an InP-InGaAs uni-travelling-carrier photodiode with a 3 dB bandwidth of 310 GHz and a FWHM of 0.97ps was fabricated.
Journal ArticleDOI
Photonic generation of continuous THz wave using uni-traveling-carrier photodiode
TL;DR: In this article, a uni-traveling-carrier photodiode (UTC-PD) is integrated with a wideband log-periodic toothed antenna for generating millimeter and sub-millimeter waves at frequencies of up to terahertz range.
Journal ArticleDOI
