Monolithically-integrated distributed feedback laser compatible with CMOS processing.
An optically-pumped, integrated distributed feedback laser is demonstrated using a CMOS compatible process, where a record-low-temperature deposited gain medium enables integration with active devices such as modulators and detectors. A pump threshold of 24.9 mW and a slope efficiency of 1.3 % is demonstrated at the lasing wavelength of 1552.98 nm. The rare-earth-doped aluminum oxide, used as t...
متن کاملA nanoelectromechanical tunable laser
The ability to tune the frequency of an oscillator is of critical importance and is a fundamental building block for many systems, be they mechanical or electronic. However, this very important function is still highly inadequate in optical oscillators, particularly in semiconductor laser diodes. The limitations in tuning a laser frequency (or wavelength) include the tuning range and the speed ...
متن کاملA Widely Tunable CMOS Gm-C Filter
This paper describes a new widely tunable transconductor that can realize a channel-select filter having both of these characteristics. The transconductor includes a new negative source degeneration resistor. The paper also discusses the measured results obtained for the 6-order elliptic LPF adopting this new circuit. We propose a new negative source degeneration resistor (NSDR) transconductor ...
متن کاملIntegrated with CMOS Driver
The emerging field of silicon photonics [1-3] targets monolithic integration of optical components in the CMOS process, potentially enabling high bandwidth, high density interconnects with dramatically reduced cost and power dissipation. A broadband photonic switch is a key component of reconfigurable networks which retain data in the optical domain, thus bypassing the latency, bandwidth and po...
متن کاملCMOS tunable linear current divider - Electronics Letters
Introduction: On-chip integrated circuits often need to be tunable to correct for process or temperature variations. However, unpredictable or unknown device characteristics make it hard to implement tunable linear circuits. In modern submicron CMOS technologies, the transistor characteristics can deviate significantly from the ideal behaviour. In this Letter a continuously tunable current divi...
