Response Characteristics of Semiconductor Lasers and Photodetectors,nt parameters of the transmitters and receivers. This chapter establishes equivalent-circuit models based on the rate equation and analyzes the response characteristics of general double-heterojunction semiconductor lasers and PIN photodetectors from three aspects: DC characteristics, transient char

Duplex Pulse Interval Modulation,ot ratio, and a strong anti-jamming ability; however, it has poor bandwidth efficiency and requires symbol synchronization. Digital pulse-interval modulation (DPIM) has a complex structure, shorter symbol length, higher bandwidth efficiency, and higher power efficiency than on–off keying (OOK) witho

m its initial dramatic expansion through to the formation of the first nuclei and atoms. From here I go to the formation of galaxies and the curious distribu tion they have taken in space. Finally I talk about the formation of elements in stars, and the first life on the planets around them.978-0-306-42952-1978-1-4899-3332-4
