“…Thus, we can see that a PM and a PBS are used to achieve a colorless full-duplex RF link with single sideband (SSB) optical carrier suppression. Besides, PM has low insertion loss and V π , and free form bias drift problems [25].…”

Microwave signals with low phase noise can be broadly used in communication systems, satellite communications, and radar systems. Discrete mode laser diode (DM-LD) has the capacity to generate signals that meet the above requirements. Moreover, it has the following advantages such as stable operation over a wide temperature range, very high side mode suppression ratio, low sensitivity to optical feedback, and narrow linewidth. In this paper, we proposed and experimentally demonstrated DM-LD for generating the second harmonic signal in the self-starting microwave generation system. The results show that DM-LD effectively reduces the single sideband (SSB) phase noise of the fundamental signals and its second harmonic signals better than the same designed experimental system using a distributed feedback LD, which reduces the SSB noise of the fundamental signal/its second harmonic signal by over 16/22 dB, 18/22 dB, 13/19 dB at a frequency offset of 10 kHz, 100 kHz, and 1 MHz, respectively.

“…However, precise electrical signal phase control and more than one optical modulator are needed [9]. Optical pulse generation using phase modulator (PM) is promising since it does not require any precise direct-current (DC) bias to the PM [10][11][12][13]. Frequency doubling can also be achieved by using an optical PM followed by a fiber Bragg rating (FBG) [11], optical interleaver [12], or silicon-on-insulator (SOI) based micro-ring resonator [13] serving as the optical notch filters to suppress the optical carrier.…”

In this work, we propose and experimentally characterize a stable 40 GHz optical pulse generation by frequency doubling using polarization rotation in a phase modulator (PM). Only half the electrical driving frequency is required (i.e. 20 GHz); hence the deployment cost can be reduced. Besides, precise control of the bias of the PM is not required. The generated optical pulses have a high center-mode-suppression-ratio (CMSR) of > 28 dB. The single sideband (SSB) noise spectrum is also measured, and the time-domain waveforms under different CMSRs are also analyzed and discussed.

“…Hence wired and wireless convergent network architectures have been proposed [2,3]. This can be achieved by transmitting both baseband and radio frequency (RF) signals simultaneously using radio-over-fiber (ROF) technologies [2][3][4][5]. Interestingly, major carriers also have a similar predication (known as Edholm's Law of bandwidth) [6].…”

Wired and wireless convergent extended-reach optical access network using direct-detection of all-optical OFDM super-channel signal

We propose and demonstrate the feasibility of using all-optical orthogonal frequency division multiplexing (AO-OFDM) for the convergent optical wired and wireless access networks. AO-OFDM relies on all-optically generated orthogonal subcarriers; hence, high data rate (> 100 Gb/s) can be easily achieved without hitting the speed limit of electronic digital-to-analog and analog-to-digital converters (DAC/ADC). A proof-of-concept convergent access network using AO-OFDM super-channel (SC) is demonstrated supporting 40 - 100 Gb/s wired and gigabit/s 100 GHz millimeter-wave (MMW) ROF transmissions.
