  • Monolithic bipolar-, CMOS-, and BiCMOS-receiver OEICs
    Thereby, according to Eq. (1)bandwidths larger than 1.5 GHz seem possible with bipolar npn transistors in the amplifier due to f~ > 10 GHz for modern 0.8 pm BiCMOS processes. For these bandwidths, bit rates of more than 2 GBit/s seem possible in the non-return-to-zero (NRZ) mode with X= 780 nm , whereby the bit rate is limited … … 0.26 ns) for the PIN photodiode with an intrinsic layer …
  • Generation of a coherent near-infrared Kerr frequency comb in a monolithic microresonator with normal GVD
    The threshold cw power was approximately the same as one in the experiment with 780 nm light. The comb generated 9.84 GHz RF signal with a high speed photodiode . … spectral purity characterized with single side- band phase noise of −106 dBc/Hz at 10 kHz frequency offset …
  • High power single-frequency 780-nm fiber laser source for Rb trapping and cooling applications
    A small amount of the 780 nm laser light (some mW) can be then sent, via a sampling output, into a saturated-absorption spectroscopy setup for frequency locking the laser emission to a rubidium transition with an error signal applied to the … The tunability of the laser is around 200 GHz by varying the seeder temperature and 10 GHz by adjusting its current. … atomic line) by measuring the beat-note frequency between both lasers recorded on a fibered fast photodiode .
  • Integrated Silicon Optoelectronics
    For the wavelengths 780 and 850 nm , a thickness of at least 10 µm is necessary for the so-called intrinsic layer of a PIN photodiode , due to the low optical ab- sorption coefficient of silicon for wavelengths larger than about 700 … … 1016 cm−3 for high-speed bipolar transistors with transit frequencies in the 10 GHz range or above.
  • Optical Interconnects

  • Design of a dual species atom interferometer for space
    We anticipate a long- term frequency stability of better than 3·10− 10 by stabilizing the laser with … A separate fibered, low-power PPLN generates 780 nm light output, which is guided towards a fiber-optical splitter system to distribute and overlap the frequency-doubled reference laser light with the light of four microintegrated diode laser modules (see Chapter 6 … The generated beat notes, typically in the GHz regime, are detected with fast photodiodes and subsequently used for frequency stabilization of the four diode laser modules.
  • Design and implementation of high-speed planar Si photodiodes fabricated on SOI substrates
    A more common approach has been to fabricate planar photodiodes on Si on insulator (SOI) wafers [6]–[ 10 ]. … that was fabricated on an SOI wafer with a top Si film thickness of 100 nm [6]. For 780 -nm excitation, the device achieved a bandwidth of 140 GHz , but its responsivity was only 5.7 mA/W.
  • Measurement of optical frequencies and frequency ratios
    Approximately 30 mW of the laser output is coupled into a piece of microstructure fibre 10 cm long with a core diameter of 1.7 µm and a zero- GVD wavelength of 780 nm [70]. Thus the 103rd harmonic of frep at 10 GHz has been detected with a fast InGaAs PIN photodiode (PD) after spectral filtering with a fused-silica etalon.
