A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Balanced tuned receiver front end with low noise and high common mode rejection ratio
A balanced optical receiver front-end suitable for Gbit/s heterodyne detection in coherent optical communication systems is presented. The transimpedance is 70 dB Ω with ±2 dB ripple over the passband from 2 to 4•4 GHz. The ripple was reduced to ±0•5 dB within a passband from 2•1 to 4•4 GHz by manual tuning of the circuit.
