“…In this work, we used a 7x15 um 2 UTC-PD that has coplanar waveguides with epitaxy structure similar to the one described in [18]. We have characterized the UTC-PD in terms of its photocurrent versus the bias voltage for different levels of injected optical power, as shown in Fig.…”

Abstract:We report the first demonstration of a uni-traveling carrier photodiode (UTC-PD) used as a 5 Gbps wireless receiver. In this experiment, a 35.1 GHz carrier was electrically modulated with 5 Gbps non-return with zero on-off keying (NRZ-OOK) data and transmitted wirelessly over a distance of 1.3 m. At the receiver, a UTC-PD was used as an optically pumped mixer (OPM) to down-convert the received radio frequency (RF) signal to an intermediate frequency (IF) of 11.7 GHz, before it was down-converted to the baseband using an electronic mixer. The recovered data show a clear eye diagram, and a bit error rate (BER) of less than 10 −8 was measured. The conversion loss of the UTC-PD optoelectronic mixer has been measured at 22 dB. The frequency of the local oscillator (LO) used for the UTC-PD is defined by the frequency spacing between the two optical tones, which can be broadly tuneable offering the frequency agility of this photodiode-based receiver.

“…In this work, an UTC-PD with epitaxy structure similar to the one presented in [13] was used as an OPM, by which an incoming radio frequency (RF) signal at 34.5 GHz is mixed with an optically generated heterodyne signal (ΔF) at 24 GHz to produce a new signal at an intermediate frequency (IF) at 10.5 GHz, as illustrated in Fig. 1.…”

Abstract-This paper presents the first demonstration of an uni-travelling carrier photodiode (UTC-PD) used as a receiver of a wirelessly transmitted quadrature phase shift keying (QPSK) signal. In this demonstration, a 1 Gbaud QPSK signal centered at 33.5 GHz was transmitted over a wireless distance of 1.4 m. At the receiver, an UTC-PD is used to down-convert the RF signal to an intermediate frequency (IF) of 9.5 GHz by mixing the RF signal with a heterodyne signal at 24 GHz. The down-converted signal is captured by the real time scope for further digital signal processing. The error vector magnitude (EVM) of the demodulated signal was measured to be 18%, which corresponds to a bit error rate (BER) of 10 -8 .

“…Figure 1 shows the schematic of the reconfigurable C-RAN developed within the IPHOBAC-NG project ("Integrated Photonic Broadband Radio Access Units for Next Generation Optical Access Networks") [7]. The C-RAN relies on three building blocks under development: a singlesideband optical modulator [8], a tunable low linewidth laser [9], and a coherent optical heterodyne detector [10]. In a RoF network based on reconfigurable C-RANs, the optical link transports the channels in baseband, and the up-and down-convertion to millimeter-wave frequencies is done locally, avoiding the two shortcomings mentioned.…”
