A tunable two-section amplified feedback laser, which employs an amplifier section as the integrated feedback cavity, is designed and fabricated for dual-mode operation with mode separation of 100 GHz. Detailed simulations and experimental characterizations on the performance of the laser are presented. Promising dual-mode emission with continuous tuning range over 16 GHz（87.41–103.64 GHz） is experimentally demonstrated.

A novel lumped electro-absorption modulator with a charge layer and an undercut ridge waveguide （DU-EAM） was fabricated and ***,two other kinds of EAM with straight ridge waveguides,one with a charge layer（D-EAM） and another with no charge layer（N-EAM）,were fabricated and tested to ensure that the design of the DU-EAM would reduce the RC-time *** measured capacitance of the D-EAM and the DU-EAM is lower than that of the N-EAM under reverse bias voltage from -1 to -8 V due to the inserted charge *** capacitances of the N-EAM,the D-EAM and the DU-EAM are 0.375,0.225 and 0.325 pF,respectively, at -3 *** addition,the DU-EAM had a larger extinction ratio（25 dB at -3 V） and higher modulation efficiency （13 dB/V between -1 and -2 V） than two other straight-ridge-waveguide ones（the D-EAM performed 22 dB and 10 dB/V,the N-EAM performed 20 dB and 10 dB/V） due to the 5.2μm wider active region.

The effects of the multimode diluted waveguide on quantum efficiency and saturation behavior of the evanescently coupled uni-traveling carrier （UTC） photodiode structures are reported. Two kinds of evanescently coupled uni-traveling carrier photodiodes （EC-UTC-PD） were designed and characterized： one is a conventional EC-UTC-PD structure with a multimode diluted waveguide integrated with a UTC-PD; and the other is a compact EC-UTC-PD structure which fused the multimode diluted waveguide and the UTC-PD structure together. The effect of the absorption behavior of the photodiodes on the efficiency and saturation characteristics of the EC-UTC-PDs is analyzed using 3-D beam propagation method, and the results indicate that both the responsivity and saturation power of the compact EC-UTC-PD structures can be further improved by incorporating an optimized compact multimode diluted waveguide.

A terahertz excitation source based on a dual-lateral-mode distributed Bragg reflector （DBR） laser working in the 1.5 μm range is experimentally demonstrated. By optimizing the width of the ridge waveguide, the fundamental and the first-order lateral modes are obtained from the laser. The mode spacing between the two modes is 9.68 nm, corresponding to a beat signal of 1.21 THz. By tuning the bias currents of the phase and DBR sections, the wavelengths of the two modes can be tuned by 2 nm, with a small strength difference （〈5 dB） and a large side-mode suppression ratio （SMSR 〉 45 dB）.
