We have developed a 1-mm-long high-power DFB laser using an asymmetrical cladding based on the dilute waveguide technique. We have obtained about 180 mW output power at 25°C and >;30 mW at 15°C-85°C chip temperature with >;55-dB sidemode suppression ratio. This temperature range allows a 9.7-nm wavelength tunability. For high output power, the relative intensity noise is lower than -160 dB/Hz in the 0.08-40-GHz frequency range and the optical linewidth is better than 300 kHz.

We report the demonstration of high-power and low relative intensity noise (RIN) directly modulated distributed feedback lasers at 1.55 μm. We have developed a structure with asymmetrical cladding to reduce internal losses due to the p-doped upper cladding. We obtain an output power of 140 mW at 550 mA and an RIN below -157 dB/Hz in the 0.1-20 GHz range along with a high side-mode suppression ratio (>;55 dB). The modulation bandwidth was larger than 7 GHz. The characteristics of these lasers, namely a high electrical to optical conversion efficiency (0.340 W/A at 350 mA), low noise, high power (98 mW at 350 mA), and linearity, make them the perfect candidates for high gain, high dynamic directly modulated analog links.

In order to achieve a high output power, high gain and high dynamic range directly modulated optical link, we have developed a high power and low noise DFB laser and a high power handling and high efficiency photodiode with specific designs. The laser exhibits high power (180 mW), high efficiency (0.4 W/A), low RIN and a 7.4 GHz modulation bandwidth. The UTC photodiode offers high efficiency (1 A/W), high saturation current (90 mA) and 15 GHz modulation bandwidth. We have realized a low loss optical link with no amplifier and no impedance matching network. We have obtained a 7.3 GHz modulation bandwidth link with a gain higher than . Third order intermodulation of the devices at various different polarization points has been investigated to deduce the optical link dynamic range. At 2.5 GHz, we have demonstrated an OIP3 of 37 dBm and a SFDR close to 120 dB · Hz2/3.

We report on the design and characterization of a high-power and high dynamic range directly modulated analog fiber optic link in the S (2-4 GHz) band. The link is amplifier free, and uses passive impedance matching networks associated to high power laser diode and high power photodiode. Thanks to the high components efficiencies, together with the benefit of reactive impedance matchings, we achieved a high gain (≥ 0 dB) over 500 MHz bandwidths. Moreover, the use of high power and high linearity components allowed us to achieve simultaneously an output -1dB compression point higher than 20 dBm, and an output third order intercept point (OIP3) of more than 31 dBm. The measured spurious free dynamic range is as high as 114 dB.Hz2/3.

We report on the development of a novel superluminescent diode (SLD) design with high output power and a wide optical bandwidth operation. The SLD combines an asymmetrical cladding structure for reduced internal losses and thick quantum wells to obtain emission from both the fundamental level and the first excited level. The

optical bandwidth is equal to 135 nm for a 2-mm long device. For longer devices, the optical bandwidth is slightly reduced but the optical output power increases. By reinjecting a part of the optical power using an external reflector we obtain 27 mW of output power.

The accurate determination of the atmospheric distribution of carbon dioxide (CO2) on planetary scale is a key requirement for setting up modeling tools able to make reliable predictions of Earth climate dynamics which are essential for the understanding of such important issues as climate change and global warming. Nowadays, the concentrations of CO2 are mainly measured in-situ at a number of surface stations that are unevenly distributed over the planet. Air-borne and space-borne missions have the potential to provide a denser and better distributed set of observations to complement those provided by the surface network.

Semiconductor light sources like light emitting diodes (LEDs) or laser diodes (LDs) are the most important light sources for space applications. LEDs are used in the control panels or lightning systems in the spacecrafts and as growth lightning systems in a deep space.

Nowadays the interest in high power semiconductor devices is growing for applications such as telemetry, lidar system or free space communications. Indeed semiconductor devices can be an alternative to solid state lasers because they are more compact and less power consuming. These characteristics are very important for constrained and/or low power supply environment such as airplanes or satellites. Lots of work has been done in the 800-1200 nm range for integrated and free space Master Oscillator Power Amplifier (MOPA) [1]-[3]. At 1.5 μm, the only commercially available MOPA is from QPC [4]: the fibred output power is about 700 mW and the optical linewidth is 500 kHz. In this paper, we first report on the simulations we have done to determine the appropriate vertical structure and architecture for a good MOPA at 1.58 μm (section II). Then we describe the fabrication of the devices (section III). Finally we report on the optical and electrical measurements we have done for various devices (section IV).
