JUNE 26, 2008 -- Kylia says it can simplify and "lighten" coherent reception architectures via a coherent receiver that obviates the need for balanced photodiodes. Standard photodiodes will be used to convert optical signals into electrical waveforms, says Kylia. Saving balanced photodiodes will make installation easier and less expensive.
Kylia uses four outputs over the eight available on the mint-2x8. In the standard mint 2x8, the input signal is polarization split and the local oscillator (LO) is spit 3 dB. Each polarization signal is mixed with the LO for a total of four outputs. Each output is offset from the previous one by 90 degrees.
Kylia says the robust nature of the component allows handling of high power. Powering significantly the LO in comparison to the signal simplifies equations and allows recovery of the incoming signal phase and amplitude with four outputs instead of eight.
The Mint-2x8 half inherits the same properties as the standard mint-2x8: compact package (68x60x6 mm), wide operating wavelength range (C+L), and a typical phase difference up to 90 degrees +/- 1 degree, according to the company.
