Direct modulation of a laser 1 has always been used in optical telecommunications. Although distance–capacity product capabilities using this approach have been limited, it represents a very ...

Abstract: The 'switching-modulator' or the 'square-law' modulator can be used for generating amplitude modulation (AM/DSB), while the 'ring-modulator' or the balanced modulator can be used to generate ...

Abstract: A center frequency reconfigurable continuous-time bandpass ΔΣ modulator is implemented in 65 nm CMOS. A new duty-cycle-controlled DAC scheme facilitates center frequency reconfiguration, and ...

CAMBRIDGE, Mass.--(BUSINESS WIRE)--HyperLight, creator of the TFLN Chiplet™ platform, today announced the launch of its groundbreaking 110 GHz Low Vπ Intensity Modulator, featuring industry-standard ...

Considerations are presented for the design of GaAs traveling-wave electro-optic modulator arrays for space data-link applications. Central to the modulator design is a low loss folded optical ...

We experimentally demonstrate a broadband electro-absorption modulator exploiting indium tin oxide (ITO) as the active switching material. Si strip waveguides are fabricated and covered with 8 nm of ...

This is my version of a C64 RF Modulator replacement based on the schematics of similar designs like Zero-X/OMS's Modified Commodore RF Modulator Design and JMP$FCE2 ...
