OSAP, a universal platform for energy conservation in the home and the workplace
The rapid evolution and spread of network technologies is leading in recent years to the connection through networks of consumer appliances, audio/visual equipment, home fixtures, and sensors as well as computers and other information devices. NTT Cyber Solutions Laboratories is conducting an OSAP (OSGi Service Aggregation Platform) research program aimed at enabling compatibility, interconnectivity, and linked control between all these devices. OSAP is a service platform for centralizing the distribution of applications and services required by home appliances, vehicles, and mobile devices connected to the network. Building this platform into connected devices is expected to help reduce complexity, save space, and cut back on energy expenditures of home and office network environments.

High speed/ultra-low power chip capable of trapping light for one nanosecond
Research is being conducted around the world to develop technologies for capturing, storing, and slowing down light. In 2006, NTT Basic Research Laboratories became the first in the world to successfully trap and store light for over one nanosecond (one billionth of one second), and slow down the speed of light propagation to less than 1/50,000 of that in air. This new technology will be applied to opto-electronic products such as optical switches, and will in the future enable the development of devices such as ultra-energy efficient photonic information processing chips*1 and optical quantum information processors*2 that operate in the realm of single photons.
*1 Photonic information processing chip
A chip used for complex information processing of ultra-high speed optical signals without the need for signal conversion. Using this chip reduces power consumption since it eliminates the need to convert optical signals into electrical signals for processing.
*2 Optical quantum information processor
A processor that relies on the characteristics of photons (the quantum units of light energy) to perform certain high speed operations such as quantum calculations and quantum encryption.

Laser module not requiring cooling system
Laser modules used as core components in optical switching systems are equipped with cooling systems to prevent degraded signal conversion performance due to high temperatures. To eliminate the need for such cooling systems and reduce overall module power consumption, NTT Photonics Laboratories has developed a working laser module that enables stable operation at temperatures even as high as 85°C.

Developing cheaper, more compact solar panels through proprietary technologies that deliver sufficient voltage even from a single small cell
In fiscal 2008, NTT Energy and Environment Systems Laboratories successfully developed an integrated circuit for the control component of a proprietary ultra low voltage input booster module to boost voltage generated even by a single photovoltaic cell to a level sufficient to run devices. This technology enables reduction of both the size and cost of solar panels, and can be used in solar powered rechargers for mobile phone and other terminals or in the recharging units of small-scale outdoor solar power supplies.

Development of an extra long wavelength semiconductor laser light source for advanced medical, environmental, and industrial applications
NTT Photonics Laboratories used its optical communications device expertise to develop a 2.3 μm-plus laser light source in fiscal 2008. Improving the active layer indium composition of the laser using a proprietary design and low temperature growth techniques enables the laser to oscillate at a wavelength of up to 2.33 μm, which was beyond the capabilities of conventional semiconducting laser technology. Since infrared beams over 2 μm can match the absorption spectrum of gases and substances such as glucose found in the human body, such lasers hold out promise for applications such as air pollution monitoring and medical measuring devices.
