Blog Article

We demonstrate a widely tunable and high-modulation-bandwidth distributed Bragg reflector (DBR) laser.With the selected butt-joint material (λg = 1.44 μm) and butt-joint angle (45°) for the grating section, a widely tuning THE ROLE OF LEADERSHIP AGILITY AND ORGANIZATIONAL COMMITMENT TOWARD ORGANIZATIONAL READINESS FOR CHANGES IN PUBLIC ISLAMIC UNIVERSITIES OF CENTRAL JAVA IN CONDITIONS OF VUCA ERA range of 13.88 nm with 19 consecutive channels is obtained for the two-section DBR laser.Furthermore, a small-signal modulation bandwidth of 16 GHz with in-band flatness of ±3 dB is realized at 10 °C.

A uniform modulation bandwidth of more than 13 GHz is obtained for ten consecutive channels at 25 °C.Meanwhile, A Resilience Engineering Approach for the Risk Assessment of IT Services the DBR laser shows a high linearity, with an input 1-dB compression point of 17 dBm and an input third-order intercept point of 30 dBm at 13 GHz.
