Abstract: We demonstrate low-threshold and single-mode operation of 1.3-μm-wavelength InP-based photonic-crystal surface-emitting lasers. A low threshold current of 21 mA and a high side-mode ...
Abstract: We fabricate and test the three-section mode-locked laser diode. The shortest pulse is 3.34ps with time-bandwidth product of 0.65. We conduct multi-tone injection locking which result in an ...
New research shows that the benefits are even greater for those enjoying eggs five times a week or more, with the risks ...
