Under the condition of non-classical distributed errors, the test for spatial dependence in spatial panel data models is still a problem waiting to be solved. In this paper, we apply the FDB (Fast Double Bootstrap) method to spatial panel data models

We demonstrate a distributed reflector (DR) laser with the distributed feedback (DFB) section and the distributed Bragg reflector (DBR) section sharing the same multiple-quantum-well structure. The DR laser exhibits a stable dynamic single-longitudin

We demonstrate the modulation bandwidth enhancement in integrated coupled DFB lasers. The coupling strength of the dual DFB is tunable duo to a SOA sandwiching in the center. The 3-dB bandwidth is increased from 8.6 GHz to 18.7 GHz under mutual injec

We developed a single mode hybrid laser based on graphene Bragg gratings (GBGs). This hybrid laser achieves single-mode, continuous-wave operation at 1540nm with a remarkable side-mode suppression ratio (SMSR) of 48dB.

We exploit distributed optoelectronic properties enabled by graphene Bragg gratings (GBGs) to realize a hybrid single-mode laser on silicon. This hybrid laser achieves single-mode, continuous-wave operation at 1540 nm with a remarkable side-mode supp
