| Summary: | This thesis presents a simple measurement system the frequency response of the direct modulation laser diode by using standard photodiodes. And has improved the problem impedance matching at the interface between the signal source and laser diode. By using impedance matching micro strip ring resonator connected between the signal source and laser diode. The frequency response of the laser diode with an accuracy comparable to that measured by the LCA, with error less than 1 dB. Including a comparison of the loss due to reflection of a micro strip resonator ring and a laser mount. That the return loss of the RF laser mount is higher than that of a micro strip ring resonator. By the frequency response of the laser diode measurement system with micro strip resonator ring to give the frequency response of the laser diodes that are more accurate. |
