Abstract

В заявке описано устройство, включающее модулятор и оптический передатчик, соединенный с модулятором и выполненный с возможностью излучения оптического луча, модулируемого данными посредством модулятора. Оптический передатчик может быть благодаря этому выполнен с возможностью излучения оптического луча, переносящего данные без использования средств пространственного ограничения, для его приема оптическим приемником для детектирования и выделения данных из этого оптического луча. Оптический передатчик может быть выполнен с возможностью излучения оптического луча с углом расхождения более 0,1° и фотонной эффективностью менее 0,05%. Фотонная эффективность определяется как отношение числа фотонов оптического луча, которые могут быть продетектированы оптическим приемником, к числу фотонов оптического луча, излученных оптическим передатчиком.
