Researchers at NTT have developed a Lambda-sacle Embedded Active Photonic-crystal (LEAP) Laser that enables 10 Gbps communications while using only 10% of the power of conventional lasers. NTT believes the technology could be used for optical cross-connects between microprocessors, yielding significant reduction in power consumption and heat.
NTT Laboratories have been developing the LEAP laser to create the world’s first continuum wave operation of a current-injection photonic crystal laser with the threshold current of 390 microamperes at room temperature (20°C-30°C). NTT Laboratories are aiming to market this laser in about 2016.
