Showa Denko K.K. has developed what it claims to be the world's first 150 mm InP semi-insulating monocrystal mirror wafers for use in the production of photodiodes and next-generation mobile phones.

The photodiodes are used in high-speed communication systems (i.e. DWDM) that offer transmission speed of 40Gbps or higher.

The InP ingot is manufactured using the company's Hot Wall LEC method for crystal growth and can handle light in the 1,300nm and 1,550nm wavelength. The company also claims that the InP wafers offer a smaller diameter compared to GaAs wafers.
