“…A microwave/millimeter-wave generation for downlink in wireless-over-fiber systems can be achieved by a highspeed photodiode [3]. On the contrary for uplink conversion, the microwave/millimeter-wave signals can be directly converted into lightwave signals by use of high-speed optical modulation technology [4].…”

We propose an x-cut LiNbO3 optical modulator using gap-embedded patch-antennas for wireless-over-fiber systems. The proposed device is composed of an array of narrow-gap-embedded patch-antennas and an optical waveguide located at the center of the gap without a buffer layer. The modulation efficiency of the proposed x-cut LiNbO3 optical modulators was enhanced by 6 dB compared to the z-cut LiTaO3-based devices.

“…A number of multiplying photodetectors have been tried by several workers for use in optical receivers. [3][4][5][6][7][8][9] Conventional avalanche photodiodes based on III-V semiconductors exhibit a large excess noise due to nearly equal values of ionization coefficients for electrons and holes. Later on, a number of APD configurations based on the concept of bandgap engineering were proposed and studied in an attempt to reduce the excess noise.…”

We present a theoretical analysis of the noise behavior of a heterojunction bipolar transistor (HBT) used as a three terminal (3T) photodetector. The use of a HBT in the photodetector mode can greatly simplify the fabrication of HBT-based optical receivers in the monolithic form. The present model takes into account the effect of the received light on the intrinsic parameters and various noise components of the HBT when used as a detector. The model enables one to determine the signal-to-noise ratio at the output and also the noise equivalent power of the HBT. The model has been applied for characterization of an InP/ InGaAs HBT used as a 3T photodetector in the 1.55-m wavelength region.
