Eblana Photonics of Dublin, Eire, a $7.75 million-funded, seven year-old spinout from Trinity College Dublin and the Irish National Microelectronics Research Centre, with funding from TLCom Capital Partners and Enterprise Ireland, which is a developer of proprietary photon-bandgap laser technology suitable for long wavelength 1310 / 1490 / 1550 nm laser diode products for high volume broadband access, enterprise, metro and SAN applications including FTTx, APON and EPON, SONET/SDH and CWDM, which are designed to:

1. Operate uncooled in simplified production packages.

2. Additionally simplify transceiver manufacture through delivering consistent performance and high quality.

3. Exhibit differentiating features including reduced sensitivity to optical feedback, circular, non astigmatic laser emission for more efficient fibre and PLC coupling and 'excellent' thermal performance.

And which:

1. In March 2003, shortly after raising a B round of $4.5 million, announced that, for use in its integrated volume manufacturing line for making lasers for broadband access, it had purchased an LDA (Laser Diode Attach) automated assembly cell from Palomar Technologies, designed to package InP laser diode assemblies onto carriers and attach and with the ability to ensure a void free eutectic solder interface needed to generate a stable transmission of laser light.

2. In January 2005 announced an agreement with Vitesse Semiconductor whereby Vitesse would manufacture Eblana's low-threshold, single-mode laser diodes on its 4" (102 mm) InP IC line using standard VIP-2Ô InP HBT process to fabricate the laser design based on Eblana's regrowth-free laser technology platform.

3. In February 2006 announced the availability of high-performance, isolator-free, single-wavelength laser diodes for IEEE 802.3ae-2002 10GBASE-LX4 applications based on its photon-bandgap technology platform, designed to provide 10 Gigabit Ethernet LX4 equipment manufacturers with a suite of single-wavelength lasers at a fraction of the price of a conventional DFB solution.

4. Also in February 2006, announced that to address FTTH GEPON PX20 and GPON markets it was setting the base price of its single-mode, isolator-free 310 nm DFB laser replacement laser diode, incorporating Eblana's NFI (nullified feedback influence) technology and providing RIN15OMA noise performance in excess of the IEEE 802.3 ah standard requirements, at $9.95 for 'sustained high volume orders' of TO56-based product versions.

5. In March 2006 announced new TO-38 based TOSAs targeted at 4 Gbit/s Fiber Channel applications in the 1310 nm wavelength band.

6. In March 2007 announced initial shipments of extended range, -40 C to 85 C, single wavelength laser diodes for GPON and other transceiver applications, and that it had extended its laser product offerings to incorporate lasers for use in IEEE 802.3ae 10 Gbit Ethernet, 10GBASE-LR/LRM/LW and 10.0 Gbit Fibre Channel applications.

7. In September 2007 announced initial shipments of ultra-narrow linewidth, low noise laser diodes emitting at lambda 1310 and 1550 nm.

8. On July 25th 2008 announced that it had extended its ultra-narrow linewidth laser diode product line to include a 400 kHz butterfly module emitting at 1550 nm for use in communications, sensor and medical applications, and had begun commercial shipments of the product.

Has announced the introduction and commercial availability of the EP1550-NLW-B, butterfly-packaged, laser diode module which:

1. Offers guaranteed emission line-width specified at 400 kHz and below (typically 350 kHz), backed by individual test data of the measured line-width shipped with the product, with highly linear light current characteristics and high side mode suppression ratio (SMSR).

2. Comprises a strained multi-quantum well discrete mode laser diode chip supplied in an industry standard, hermetically sealed 14-pin butterfly integrated with optical isolator, thermo-electric cooler , thermistor and power monitor photodiode.

3. Typically offers 6 mW output power to specifiers in the coherent communications, sensors, medical device and imaging equipment industry sectors for use in optical-sensing, light detection and ranging(LIDAR), interferometry and T&M applications.

4. Is already in use for high bandwidth coherent communications applications where, for example, high spectral efficiency, phase encoded signals are used to overcome transmission bottlenecks.
