چکیده
Several application, like frequency chirped lidarradar system, opticdwireless communications and biomedical imaging, require optical transmitters that can generate rapidly tunable, low phase noise and low intensity noise millimeter wave sub-carriers. Using an electro-optic Nd:LiNbOJ microchip laser in an optical heterodyning scheme, we designed a simple, robust, monolithic and low-cost optical transmitter, that can generate tunable sub-carriers from DC to 5OGHz. Furthermore, we will demonstrate that due to the unique approach, whereby the tuning and lasing occur within the same crystal, the dynamics of the tuning process is fast. Index Terms Microchip lasers, lidar system, Nd:LiNbO& millimeter-wave generation.

Rapidly Tunable Millimeter-Wave Optical Transmitter for Lidar–Radar
This paper reports on the optical generation of a rapidly tunable millimeter-wave subcarrier for lidar–radar. The millimeter-wave signal is generated by beating the output from two Nd : YVO4/MgO : LiNbO3 electrooptical monomode microchip laser sections realized monolithically in a single composite crystal. The device has a continuous tuning range up to 45 GHz. The measured chirp rate is 3816 TH...

A highly tunable millimeter-wave subcarrier signal is generated by optically injecting a Fabry–Perot semiconductor laser. The optically injected light, which enables microwave subcarrier frequencies well beyond the injected laser’s free-running relaxationoscillation frequency, is then on–off keyed by direct-current (dc) modulation of the injected slave laser. Adjustment of the subcarrier freque...

pulses is also measured with respect to the gate voltage and is shown in Fig. 3. The transmission decreases linearly proportional to the positive voltage. The best fit to this transmission versus voltage plot is obtained with a damping rate of 10 THz. Consequently, it gives a mobility of 110 cm~/v-sec. We have shown that the MOS inversion layer mobility can be measured without s o m e and drain...
